“Who?” I said. None of us had heard this before. It seemed to me Lockwood had a vaguely evasive air.

Kipps sensed it too. “I trust it’s a proper agent, and not some weirdo friend of yours, Tony, brought in to make up the numbers.”

“Well—”

“Here I am, Locky.” We turned and looked back across the hall: there, just emerging from the revolving doors, with the rips in her long blue puffer jacket catching on the handle and her Wellington boots leaving a delicate trail of greenish mud on the marble floor, was Flo Bones. Through the window glass behind her, the doorman’s face could just be seen—bog-eyes popping, jaw lolling—staring after her in horror and bafflement. To be honest, Kipps’s team looked much the same, and even Holly Munro’s smooth calm was momentarily ruffled. Flo had her damp, stained burlap bag over her shoulder; as she approached she slung it off onto a pile of lavender pillows, unzipped her jacket, and bent her arms up in a languorous stretch. We got the unwashed shirt, the holed sweater, the frayed rope belt holding up her jeans; oh, yes, and the tidal smell. It was the full works.

“Ooh, that’s better,” Flo said. “Me corns are killing me today. So, Locky, aren’t you going to introduce me to these nancies? Actually, don’t bother—I can guess ’em well enough from your descriptions. All right, then, are you Kipps? Heard a lot about you and those nice plastic jewels you’ve got pasted on your rapier hilt. I can get you more like that. They wash up sometimes on Woolwich beach, just below the crematorium.”

Kipps looked like he had been slapped between the eyes with a dead fish; as, in an olfactory sort of way, he had. “Er…no. No, thank you. And you are?”

“Florence Bonnard. Accent on the second syllable, if you don’t mind. You must be Kate Godwin—bit thinner than I expected, but there’s no escaping that chin. And you”—Flo grinned enigmatically at Bobby Vernon—“I’m very pleased to see you, Bobby. Ask me what my bag’s for.”

Vernon had edged slightly away. “Er…What is your bag for?”

“That,” Flo said, “is my relic-bag. To put things in.” She leaned close to Bobby. “Things I find in the soft, moist darkness of the river mud….Want to look inside? I could pop you right in, you’re that small.”

Vernon gave a squeak and vanished behind Kate Godwin; now Flo turned to Holly Munro. I must admit I was looking forward to this bit, but our assistant preempted Flo’s advances. She strode forward, hand outstretched. “Holly Munro, Anthony Lockwood’s new assistant. Very pleased to meet you.”

I waited for the verbal assault; or, better yet, a quick over-the-head toss into the lavender cushions. But Flo seemed taken aback. Her eyelashes fluttered; beneath her grime, I swear she flushed. “Charmed, I’m sure.”

They just shook hands. Somehow, this annoyed me too.

“Right,” Lockwood said. “Good. Everyone knows each other. So let’s get started. The manager’s waiting.”

“I’m not sure we should bother….” Kate Godwin was still eyeing Flo. “Surely it’s a safe bet all the ghosts will have scarpered now.”

The current chairman of Aickmere Brothers, Samuel Aickmere, represented the fourth generation of the family to run the store. He was a fussy, nondescript man (middle-aged, bland-featured, with hair that had started, rather timorously, to recede) who had tried to make himself less so by way of his clothes. He wore a dark wide-shouldered suit with a strong purple pinstripe. A purple handkerchief, crisply folded, jutted like a potted plant from his breast pocket. The cuffs of his shirtsleeves seemed slightly longer than necessary; you could scarcely see his fingers. His tie was shockingly pink; I sensed Lockwood flinching as he shook his hand.

Mr. Aickmere cast his eyes over our rapiers and workbags without pleasure. As we explained our purpose, his lips pressed tightly together.

“Quite impossible, I’m afraid,” he said, once Lockwood finished. “This is a reputable commercial establishment. Can’t have your sort in here.”

We looked at him. Aickmere’s office wasn’t particularly large. Sure, it had room for a marble-topped desk, chair, garbage can, filing cabinet, and dark green yucca plant. One or two submissive employees standing in front of the desk, caps in hand, might just have squeezed in too. But eight hard-bitten agents, bristling with rapiers, flares, and grim-faced purpose? We must have been quite an unnerving sight, standing there—and that was before you assessed us individually. George was just finishing a tuna sandwich, holding his hand underneath to catch the falling flakes. Bobby Vernon sported his enormous salt-gun. Kipps was Kipps. Flo was Flo. I kind of understood the guy’s point.

“Mr. Aickmere,” Lockwood said, “there is a major spectral incident going on all around you, a stone’s throw from your door. You understand that we are empowered to investigate its cause, wherever that might be?”

“It is ridiculous to look here! We have no dangerous Visitors in Aickmere’s!”

“In Chelsea? Really? That’s a remarkable claim.”

“There was some little trouble, a dozen or so years ago. It was swiftly dealt with.”

“That would have been the air-raid wardens?” George said.

“I don’t remember the details.” The man waved one sleeve at us airily. “But after the event, the building was reconstructed with supernatural safety in mind. We have iron laced into the foundations and into many walls. Our staff wear silver brooches and are trained in all necessary Visitor defenses. There are lavender sticks and Rotwell salt-sprays in every room. Why? Because our customers expect and demand a safe shopping experience. And they get it—of course they do. We have a whole silversmithing department, for heaven’s sake! No, there is no need for you to linger here.”

“We’ll be very discreet,” Lockwood said.

The manager smiled at us; the smile was a tight, hard thing, a line of defense scratched across rock. “I know what DEPRAC’s like. Closing honest shops down. Bolder’s in Putney. Farnsworth’s in Croydon. That won’t happen here.”

“No one’s trying to get you closed down,” Lockwood said. “And if there is anything to be found, it’s in your interests to have it cleared.”

“Agents leave devastation in their wake! They disrupt smooth service and endanger innocent lives!”

“George, how many of our clients have we managed to kill now?”

“Hardly any. A very small percentage.”

“There. I hope that reassures you, Mr. Aickmere. We will conduct quiet investigations and be on our way.”

“No. It’s my final word.”

Lockwood sighed; he rummaged in his pocket. “Very well, I have here a DEPRAC warrant card, signed by Inspector Montagu Barnes, which—”

“Allow me.” Kipps stepped forward. “Mr. Aickmere, my name is Kipps. I’m a team leader for the Fittes Agency, and one of my areas is Public Safety Noncompliance. We take refusal to adhere to operative statutes very seriously and have the power to authorize a detainment team to exercise immediate penal restraint in such circumstances.” He put his thin, pale hands together and cracked his knuckles like a rifle volley. “I do hope that this won’t be necessary in your case?”

Aickmere blinked at him. “I can’t say. I haven’t a clue what any of that means.”

“It means,” Kipps said, “let us do our job, or we’ll lock you up. That’s basically the size of it.”

The manager sat back in his chair. He removed the purple handkerchief from his pocket and dabbed at his forehead. “Ghosts after dark, children running amok…What an age we live in! Very well, do what you must. You won’t find anything.”

Lockwood had been staring at Kipps. “Thank you, sir. We appreciate it.”

“It’s a bit late for courtesy now….Well, I have one stipulation! I insist you don’t disturb any of our displays, particularly our Seasonal Creations.”

“Seasonal Creations? Oh, you mean like the tree thing in the foyer?”

“That ‘tree thing’ is ‘Autumn Ramble,’ hand-created by noted installation artist Gustav Kramp. Did you know that every piece of dry driftwood and tissue leaf has been personally glued by hand? It took an age to piece together, and it’s very, very expensive. I simply won’t have you ruining it.”

“We’ll certainly try to be careful,” Lockwood said, after a short pause.

“We run a tight ship here at Aickmere Brothers,” Mr. Aickmere said. “Everything in its proper place.” As if to prove it, he adjusted two pens beside the blotter in the center of his desk. “And my staff cannot be distracted from their duties.”

“Certainly not. We’ll be sure to treat everything in your store with appropriate respect—right, everyone?”

We nodded. George leaned in close to me. “Remind me to blow my nose on ‘Autumn Ramble’ when we get downstairs.”

“One thing,” Lockwood said, as we were filing out. “You say you have no dangerous Visitors here, yet you give your people silver brooches. Does that mean—?”

“Oh yes, the place is haunted. ’Course it is. Where isn’t, these days?” The folded handkerchief at Mr. Aickmere’s breast lolled forward as if waving us toward the door. “But my staff are quite safe. If you wear your silver, keep your eyes open, and lock up during daylight, there’s nothing to trouble you here.”

But the chairman’s view was not entirely backed up elsewhere in the building.

“Mornings are all right,” the attendant in Men’s Wear said. “And late afternoons, funnily enough, when you get the sunlight streaming through the windows. It’s noon I don’t like, when the streets outside are bright, and in here it’s full of shadow. The air goes thick. Not hot, exactly. Just stuffy. You smell all the cardboard and plastic wraps piled in the basement, the ones we’ve taken off the new clothes.”

“Is it a bad smell?” Lockwood asked.

“No…Gets a bit much, that’s all.”

“I don’t mind it when it’s busy,” the young woman in Cosmetics said. “When there’s people coming through the doors. Quiet times, I have to pop out. Talk to the doorman, get a breath of air.”

“Why?” I asked her. “What makes you go outside?”

“The air’s so still. Oppressive. I think the air conditioning units aren’t up to snuff.”

Four other staff members, working on separate floors, also had comments to make about the general atmosphere and the apparent deficiencies of the air conditioning. But in Handbags, Belts, and Leather Goods, Miss Deidre Perkins, 55, a tall, thin-lipped person dressed in somber black, was more concerned with something else.

“If there is a Visitor,” she said at once, “you’ll find it on the third floor.”

I looked up from my notebook. Holly Munro, interviewing staff nearby, also drew near. “Really? Why?”

“Karen Dobson saw it there. She came down from Lingerie with a face like all horrors. Just before closing one afternoon in September, it was. Said she saw it at the far end of the passage.” Miss Perkins sniffed disapprovingly. “She may have been lying. Karen did have a tendency to exaggerate. I never saw anything.”

“I see. So this was an actual apparition? And before dark?”

“It was a Visitor, yes.” Miss Perkins was one of those people who avoided using ghostly terminology if at all possible. “Night hadn’t fallen, but it was a stormy day. Already very dark outside. We had the lamps on.”

“Perhaps I could speak to Karen. Which department does she work in?”

“She doesn’t, anymore. She died.”

“Died?”

“Sudden-like, at home.” Miss Perkins spoke with gloomy satisfaction. “She smoked. Expect it was her heart.” She adjusted a rack of hanging belts, smoothing them between her hands. “I suppose she’ll be a Visitor now, and all.”

“It doesn’t work that way,” I said.

“How do you know?” Miss Perkins’s facade cracked; all at once there was anger in her voice. “How do any of you know how or why our friends or family choose to come back? Do you ask the Returned their motivation?”

“No, ma’am, we don’t,” Holly Munro said. “It’s not considered wise.”

Holly glanced at me, then, as I knew she would. In the Wintergarden house, I’d done precisely that. And much good it had done me. I pressed my lips together.

“And this figure that Karen Dobson saw?” I prompted. “Did she describe it?”

Miss Perkins had moved on to a tray of purses and wallets. “Thin thing on all fours. Crawling down the corridor toward her.”

“Nothing more about its appearance?”

Her bony fingers moved across the tray, adjusting, adjusting, adjusting. “Little girl, I don’t think she hung around long enough to find out.”

A couple of hours we took, wandering around that store. I spent a good deal of it on my own. I interviewed the staff, but I also took stock of the building itself, tried to make a connection, suss out its personality. I found it surprisingly hard to do.

The layout was clear enough. It was a typical old-style department store, with each floor divided into formal sections. We had Bargains in the Basement; and Cosmetics and Visitor Defenses on the Ground floor. Visitor Defenses—consisting of more cut-price iron than you could shake a nightstick at—occupied, rather forlornly, the old Arabian Hall, looking almost comically insignificant beneath the golden pillars and winged griffins. Ladies’ Fashions, Kitchenware, and Children’s were on One; Men’s Wear was on Two, together with Habadashery and Home Furnishings. Three was mostly taken up with Furniture, while Four was Office Supplies and a few meeting rooms. To my eyes, the quality of goods seemed a little tired, though Holly Munro claimed that some of the ladies’ fashions were okay. There were four elevators—two centrally placed ones for customers (on the Ground floor, these were accessed behind the escalators) and two for staff at the north and south ends of the building—and also four staircases. Most people used the central staircase, which was next to the escalators and was impressively fashioned from coffee-colored marble, but there were narrow flights of stairs at the north and south ends too, extending the height of the building.

At the back of Aickmere’s, each floor had a long, echoing storeroom, accessible only by staff, where goods were piled in rows of cardboard boxes before being made ready for display. George spent his time prowling around these rooms, particularly the one at basement level, but I couldn’t feel any particular psychic difference in them. In fact, the sensations I got from the whole place were fairly muted—perhaps odd, given our theory that it was the focus for the whole Chelsea thing.

That’s not to say there was nothing. Underlying it all, fading in and out as you passed Visitor Defenses or the wall racks of lavender beside each interconnecting door, was a faint yet palpable unease. It was like a tingle on the skin, a prickling in the stomach; familiar to me, but not the usual malaise, chill, or creeping fear. As the afternoon drew on and the flow of customers ebbed away, the sensation grew stronger. Around me, silent staff members, pale and preoccupied, locked up registers, and tidied up displays. I went to a quiet corner, opened my backpack, and twisted the tap at the top of the ghost-jar.
