Just on two o'clock. The walk up from Hampstead Heath station had been uncomfortably hot, but here beneath the overarching canopy, the air was cool and damp. I had been in London just three days, and already I felt more at home than I ever had in Mawson. The transformation was extraordinary. On Saturday afternoon, after settling into my new, clean, high-rise hotel near St Pancras, I had wandered for hours through leafy streets and squares, breathing deep lungfuls of warm, diesel-laden air as if I had just arrived at a mountain health resort. People no longer avoided eye contact with strangers. The mountains of garbage had shrunk to a few isolated middens. Even the dogs seemed to have cleaned up their act.
I strolled up to the end of the lane and back, weigh ing the heavy bunch of keys in my hand. No one would know there was a house hidden behind the massive trees, some of them sixty or seventy feet high. I wondered how high they had been when Abigail Hamish had stood shivering here, just a few months short of fifty years ago, at the end of autumn. Most of the branches would have been bare.
Miss Hamish, as I had learned from Mr Grierstone's secretary a few hours ago, was now resting comfortably and would be in touch with me as soon as she felt well enough. She wasn't up to visitors, but I could certainly send her some flowers; they would be happy to arrange that on my behalf.
And for the first time in my life, I knew exactly where Alice was. In the National Hospital for Neurology and Microsurgery in East Finchley, less than an hour's walk across the Heath from Ferrier's Close. I had promised not to visit, or ring the hospitaclass="underline" Alice thought it would bring bad luck. She wanted to come to me, with no warning-'it'll be too awkward and formal otherwise'. Like a bride and groom keeping apart on their wedding day, not seeing each other until the ceremony. 'I want to save everything from now until we meet,' she'd said in her last message. She was spending long hours in physiotherapy, gaining strength every day. 'My feet haven't forgotten how to walk. I'm aching all over, and it feels wonderful. Nothing can go wrong now. Enjoy your house'-Alice was convinced that Miss Hamish meant to leave the whole estate to me-'and its mysteries, and soon-maybe sooner than you think-you'll hear a tap on the door.'
Secretly I agreed with her about the estate, but I didn't want to tempt fate by saying so: Miss Hamish might have another stroke and die before she'd met me. In which case the estate would presumably go to charity, or some distant Hamish relative; she sounded quite alone in the world. Tempting fate or not, I couldn't help imagining us arriving at Miss Hamish's place in the country-which had grown, in my fantasy, into a tall, rambling house with sweeping lawns and ancestral oaks-into Staplefield, in fact.
Though miss Hamish hadn't replied to any of my questions about Staplefield, that might well have been out of delicacy-for the same reason she hadn't yet given me her address. The destruction of Staplefield would have been a huge and traumatic event; Anne would have talked about it. Whereas if the house had survived, it was quite possible that Miss Hamish, once she'd been appointed executor, had decided to rent Staplefield from the estate. Or simply to live there: as the sole beneficiary of Anne's will, her only legal duty had been to herself. She just didn't want to tell me, until the time came for us to meet, that my mother had lied about the fire.
Back in Mawson, reading and re-reading Miss Hamish's letter in the chilly hallway, a ghastly suspicion had leapt off the page. It had obviously never occurred to Miss Hamish-she could never have written so openly if it had-that Phyllis Hatherley might have murdered her sister. Everything fitted perfectly: Phyllis and her aunt quarrel violently; Phyllis is disinherited and leaves home in a rage; her aunt dies suddenly (and very conveniently) within weeks, leaving everything to sweet-natured Anne, who immediately makes a will leaving everything to her best friend Abigail. Why would a girl of twenty-one make such a will, unless she was afraid of her sister? But Anne doesn't know where Phyllis is, so she can't tell her about the will. Until, perhaps, it's too late. Phyllis discovers she's killed her sister for nothing, and that's the last we see of her until she turns up in Mawson a decade later.
It had seemed horribly plausible, until I realised that the same thing must have occurred to the police and the lawyer. It would have been their first line of inquiry. And they would have questioned Abigail Hamish about Phyllis: they would have wanted to see Anne's letters. So the police, and the lawyer-and therefore Miss Hamish- must have been satisfied that Phyllis was innocent. Otherwise Miss Hamish would never have trusted me with the keys to Ferrier's Close.
Or so I had persuaded myself. There were at least a dozen keys on the ring: three pitted gunmetal Banhams; two for spring locks, and several household keys, very worn and tarnished, for barrel-locks of various sizes. The door itself was curved at the top and recessed into the brickwork. It had weathered to a pale greenish grey, mottled with lichen; lines of moss sprouted between the vertical planks. A discoloured nameplate, a brass mailslot, locked or corroded shut, a latch and a keyhole. No bellpush or speaker grille; no way of making your presence known except to pound with your bare knuckles on the swollen timbers of the door.
The second of the Banham keys fitted the lower keyhole: the snap as it turned over was startlingly loud. I lifted the latch and pushed, against resistance. To my surprise the door opened silently.
I was standing at the entrance to a tunnel about eight feet high, formed by hooped metal frames over which branches of some kind had been trained. Dim twilight filtered through an arched roof of dense greenery; a few spots of sunlight glowed on the flagged stone floor. At the far end, some thirty feet away, I could just make out two steps leading up to another door. Vines and creepers and climbing roses had grown up amongst the gnarled branches; the metal hoops were heavily corroded. But the inside of the tunnel had been recently pruned. The clipped ends of vines and shoots were still sharply defined, the dark, lichen-stained flagstones bare except for a scattering of leaves.
I withdrew the key and let go of the street door. It closed behind me with a faint hiss. The spring lock clicked shut; suddenly fearful, I snatched at the knob to make sure I wouldn't be trapped.
It had been quiet in the lane outside, but you could still hear the faint hum of traffic from East Heath Road, the occasional howl of an accelerating motorbike, the distant whine of a jumbo from the endless queue descending towards Heathrow. With the closing of the gate, all of those sounds had ceased. The tick-ticking of my pulse was suddenly louder. I set off along the path, accompanied by faint rustlings and stirrings. Birds, I hoped, though I couldn't see any. The surrounding vegetation was impenetrably dense.
At the far end, the sides thinned out enough to allow glimpses of red brick and stonework, and the light was a little better. Though the tunnel-what was the word?-espanniered?-no, pleached-extended all the way to the porch, you could see where the original structure had ended and another section had been added, also many years ago, by the look of the gnarled vines overhead. I went up the two steps into a porch, only a few feet deep, with solid brick walls on both sides. It looked as if there had once been vertical windows on either side of the door, but the apertures had been bricked up. No glass in the door, either. Its dark green paint was cracked and peeling.
