A magpie lit on the gate a few feet from her car and examined her, its bright, beady eye mocking, as if it knew the truth about her. She’d worked so hard at showing she could do the job, at fitting in – had she blown it all that morning? What would her station officer say when he heard she’d gone back to the scene, off duty, without clearing it with him first? Charlie Wilcox was a good boss, a fair man who preferred encouragement to criticism, but she had a sinking feeling that she’d violated some unwritten protocol, made a fool of herself, and by association, of her watch. There was nothing worse than that. The magpie took off with a sharp clap of wings, and her shoulders jerked involuntarily.

What had possessed her? Had she been afraid she’d missed something, made some mistake that would come to light? In the three years she’d been in the fire service, she’d only worked half a dozen large structure fires, and last night was one of the few times she’d had the nozzle. To have the nozzle, be first on the hose, that was what every firefighter lived for – it was the ultimate experience, it was what made you real. She could still feel the exhilaration in her veins, and in an instant of clarity she knew she hadn’t done anything wrong, she’d simply done what she’d been trained to do, and she’d never felt more whole in her life.

Then why did her brain keep replaying the spongy feel of flesh beneath her gloved hand, the glimpse of the contorted face with the bared and blackened teeth? She’d seen worse, for God’s sake – why did this one somehow seem to be her responsibility?

She had to let it go. She had to sleep or she’d be useless on her watch tonight. That she couldn’t afford, especially with the FIT coming in to question the rest of the watch. Her visit to the fire scene was bound to come out; there was no avoiding it. She’d just have to take her lumps from Wilcox and the others, if necessary, and put the whole episode behind her.

With that resolution, she blew a few stray hairs from her face and got out of the car. But as she let herself into the quiet house, she found herself thinking about the coming evening, wondering if the FIT officers would have any new information, and if the superintendent from Scotland Yard would be there as well.

Not wanting to say anything about her discoveries in front of Fanny, Gemma waited until the constable had come and gone, then spoke briefly to Winnie as they stood outside the church office.

Winnie shook her head in bewilderment. “Why go to so much trouble to secrete things away, when she knew Fanny couldn’t climb the stairs? And why hide the things at all? Don’t most single women have a few pairs of sexy knickers?”

“If they don’t, they should,” Gemma replied, grinning. In spite of her newly married status, Winnie could still display an endearingly innocent honesty. “What about the phone?” she asked. “Do you suppose Elaine thought Fanny would be a nuisance if she knew she could reach her on a mobile?”

“It’s always seemed to me that Fanny goes out of her way not to make demands on Elaine.” She shrugged. “But maybe Elaine perceived it differently. I can’t guess at this point. Should we have told the constable about these things?”

“I don’t think having a stash of slightly tarty clothes and a mobile phone constitutes significant detail. But it has made me curious,” she added. “Will you let me know if she turns up? Do you think Fanny will be all right?”

“I’ll look in on her this evening,” Winnie told her. “Thanks for all your help.”

After a quick hug, Gemma went on her way, cutting up Blackfriars Road into Union Street. The rain had begun again, a drizzle too light for umbrellas but heavy enough to be annoying. She turned up the collar of her coat and clutched it closed at her throat, trying to keep the occasional drops from slipping down the back of her neck.

There was one thing she’d noticed that she hadn’t felt comfortable sharing with Winnie. Fanny had frequently used the past tense when talking about her friend, although she’d corrected herself a few times. Did she know more about Elaine’s disappearance than she’d let on?

“That’s a nasty suspicious mind you’ve got,” Gemma chastised herself aloud, earning a surprised glance from a passing man in a pin-striped suit. The woman was confined to a wheelchair, for heaven’s sake, she went on to herself – she couldn’t possibly have had anything to do with her friend’s mysterious disappearance.

And Gemma certainly had enough on her plate, with her own caseload and Kit’s hearing coming up on Monday, without taking on another problem. She’d lost half her afternoon as it was, and she imagined Melody Talbot beleaguered, ready to send out a search party for her. Fishing her phone from her bag, she gave Melody a quick call, explaining that something had come up but that she was now on her way back to the station.

Her ruminations and her phone call having taken her as far as Southwark Bridge Road, she took a moment to orient herself before turning north, towards the river, then right into Southwark Street. She caught sight of the distant cluster of emergency vehicles almost immediately, but it wasn’t until she was almost upon them that she was able to see the scene of the fire itself.

Her first thought was one of regret, for the building had been beautiful, its form and symmetry a striking example of the best of Victorian architecture. How could someone willfully damage something so lovely? she wondered, then remembered that Kincaid had called it a suspicious fire. It might not have been arson.

The appliances had gone, but the generator lorry remained, and against the gray sky the lower windows of the warehouse glowed with the eerily bright light of the arc lamps. Piles of blackened rubble had been raked out onto the pavement, and even from a distance the stench made her throat constrict.

There were several marked police cars and a couple of unmarked but vaguely official-looking vans. She recognized Doug Cullen’s slightly battered Vauxhall Astra pulled up over the curb. She was about to ask one of the constables guarding the perimeter where she might find Kincaid when she saw him, standing a few yards down the side street with Cullen and a dark-haired woman in a tan coat.

Gemma’s lips curved in an involuntary smile; familiarity hadn’t dulled the jolt of pleasure she felt on seeing him after a few hours’ separation. Then he looked up and saw her, his eyes widening in surprise.

“Gemma!” he said, hurrying towards her. “What are you doing here? Is everything all right? The boys-”

“No, no, they’re fine,” she hastened to reassure him. “It’s just that I was in the area – Winnie rang and asked me to lunch – and I thought I’d stop by and see how you were getting on.”

“Very slowly,” he said, slipping an arm round her shoulders for a quick hug and giving her a grin that told her he was glad to see her as well.

Gemma realized that the dark-haired woman was watching her with a less than welcoming regard. “I don’t want to trespass on your patch. If it’s inconvenient-”

“You’re fine. Don’t worry about the grim-visaged Inspector Bell,” he added in her ear. “She improves as she thaws. We’re just about to have a word with the woman who reported the fire. Come along with us – I’ll be glad to have your take on this. Then you can tell me about Winnie.”

They’d reached the others. Doug Cullen took her hand warmly, then introduced her to DI Maura Bell. Bell put out her hand in response to Gemma’s, but jerked it free after the slightest press of fingers. Slam-bam-thank-you-ma’am, Gemma thought, amused. This was a woman who obviously did not relish physical contact or having an uninvited investigator on her case.

“While we’re waiting for the fire investigation officer, Bill Farrell, I can give you a quick rundown of what we have so far,” Kincaid said, ignoring Bell’s scowl. “The building belongs to Michael Yarwood, the MP, who was in the process of turning it into luxury flats with a restaurant on the ground floor. The emergency call came in just after half past twelve last night, and the fire was well involved by the time the brigade arrived. They entered through the front door, which they found unlocked, and they later discovered the side door unlocked as well.” He gestured towards the door facing them across the narrow side street. The rear of the building jutted out in a sort of attached tower with a window at each level, leading Gemma to assume that the door opened into a rear staircase.
