“And it was too late by then.”

“What do you mean?”

“Everybody was dead.”

“Yes… well, I tried to tell them how dangerous it was, living there. I suspect one of them must have had a dodgy heater of some sort, too, as well as the turpentine. I know it’s been a mild winter, but still… It is January.”

“Mr. Hurst,” Annie asked, “what were you thinking when you saw the fire’s glow above the tree line and got on your bike?”

Hurst looked at her, a puzzled expression on his face. “That I had to find out what was happening, of course.”

“But you said you already knew at once what was happening.”

“I had to be certain, though, didn’t I? I couldn’t just go off half-cocked.”

“What else did you think might have been causing the orange glow?”

“I don’t know. I wasn’t thinking logically. I just knew that I had to get down there.”

“Yet you didn’t do anything when you did get down there.”

“It was too late already. I told you. There was nothing I could do.” Hurst sat forward, chin jutting aggressively. He looked at Banks. “Look, I don’t know what she’s getting at here, but I-”

“It’s simple, really,” said Banks. “DI Cabbot is puzzled why you decided to cycle a mile – slowly – down to the canal branch, when you already knew the boats were on fire and that the wood they were made of was so dry they’d go up in no time. I’m puzzled, too. And I’m also wondering why you didn’t just do what any normal person would have done and call the bloody fire brigade straight away. From here.”

“Now there’s no need to get stroppy. I wasn’t thinking clearly. Like I said, you don’t when… when something like that… The shock. Maybe you’re right. Looking back, maybe I should have phoned first. But…” He shook his head slowly.

“I was waiting for you to say you hurried down there to see if there was anything you could do,” Banks said. “To see if you could help in any way.”

Hurst just stared at him, lower jaw hanging, and adjusted his glasses.

“But you didn’t say that,” Banks went on. “You didn’t even lie.”

“What does that mean?”

“I don’t know, Andrew. You tell me. All I can think of is that you wanted those narrow boats and the people who lived on them gone, that you didn’t call the fire brigade the minute you knew they were on fire, and that as soon as you got home you put your clothes in the washing machine. Perhaps nobody can fault you for not jumping on board a burning boat, but the fifteen minutes it took you to cycle down the towpath and make the call could have made all the difference in the world. And I’m wondering if you were aware of that at the time, too.” Banks looked at Annie, and they stood up, Banks grabbing the bag of clothes. “Don’t get up,” he said to Hurst. “We’ll see ourselves out. And don’t wander too far from home. We’ll be wanting to talk to you again soon.”

Banks wasn’t the only one who saw his weekend fast slipping away. As Annie pulled up outside the Victorian terraced house on Blackmore Street, in south Eastvale, blew her raw nose and squinted at the numbers, she realized that the fire on the barges, or narrow boats, as Andrew Hurst had insisted they were called, was probably going to keep her well occupied for the next few days. She had been hoping that Phil Keane, the man she had been seeing for the past few months – when work and business allowed, which wasn’t all that often – would be coming up from London for the weekend. Phil had inherited a cottage in Fortford from his grandparents, though he had grown up down south, and he liked to spend time there no matter what the season. If Phil didn’t make it, Annie had planned to spend her free time getting over her cold.

Annie got out of the car and looked around. Most of the houses in the area were occupied by students at the College of Further Education. The area had been tarted up a lot since Annie had started working in Eastvale. What had once been a stretch of marshy wasteground between the last straggling rows of houses and the squat college buildings was now a park named after an obscure African revolutionary, complete with flower beds that rivaled Harrogate’s in spring. A number of cafés and a couple of fancy restaurants had sprung up there over the past few years, too. Students weren’t as poor as they used to be, Annie guessed, especially the foreign students. Many of the old houses had been renovated, and the flats and bed-sits were quite comfortable. Like the rest of Eastvale, the college had grown, and its board knew they had to work to attract new students.

This morning, though, in the clinging January fog, the area took on a creepy, surreal air, the tall houses looking like a Gothic effect in a horror film, rising out of the mist with their steeply pointed slate roofs and elaborate gables. Through the bare trees across the park Annie could see the lonely illuminated red sign of the Blue Moon Café and Bakery offering cheap breakfasts. For a moment, she considered going in and ordering fried eggs, mushrooms and beans on toast – skipping the sausage and bacon because she was a vegetarian – but she decided against it. She’d grab something more healthy later, back in the town center. Besides, she thought, looking up at the looming house, she had an alibi to check.

She walked up the steps and peered at the names on the intercom box. Mandy Patterson. That was the person she wanted. She pressed the bell. It seemed to take forever, but eventually a sleepy voice answered. “Yes? Who is it?”

Annie introduced herself.

“Police?” Mandy sounded alarmed. “Why? What is it? What do you want?”

Annie was used to that reaction from members of the public who either felt guilty about some driving or parking offense or didn’t want to get involved. “I just want to talk to you, that’s all,” she said in as convincing a friendly voice as she could manage. “It’s about Mark.”

“First landing, flat three, on your left.”

Annie heard the door release click and pushed it open. Inside, the place was far less gloomy than out. The thick-piled stair carpets looked new, the hallway was clean and well kept, the interior well lit. Better than the student digs of her days, Annie thought, even though those days had been only about fifteen years ago.

Annie climbed the steep stairs and knocked on the door to flat three. Fit as she was, she was glad Mandy didn’t live all the way at the top. The damn cold was sapping her energy, making her feel dizzy when she exerted herself. She couldn’t meditate, either. All she experienced when she sat in the lotus position and tried to concentrate on the breath coming and going as it passed the point between her eyebrows was either a stuffed-up nose or a thick, phlegmy sniffle.

The girl who opened the door looked as if she had just been woken up, which was probably the case. She rubbed her eyes and squinted at Annie. “So you’re the police?” she said, looking at Annie’s army greatcoat, long scarf and high boots.

“Afraid so.”

Annie followed her into the room. Perhaps because Mandy had heard over the intercom that Annie was female, or perhaps because seminudity didn’t concern her, she hadn’t bothered putting anything on other than a long white T-shirt with a George and Dragon logo on the front. Annie thought it was too cold for such scanty clothing, but she could soon feel that the bed-sit was centrally heated. Another change from her own student days, when she had braved a dash from the piled blankets to the gas fire and hoped to hell her five pee from last night hadn’t run out. She took off her overcoat and found that she was warm enough without it.

“You woke me up, you know,” Mandy said over her shoulder.

“Sorry about that,” Annie said. “Part of the job.” The messed-up sheets on the mattress under the window testified to what Mandy said.

“Cup of tea? I’m having one myself. Can’t think in the morning without a cup of tea.”
