A wave of weakness washed over me. I nearly fainted.

There, just inches from my invading eyes, cradled in tendrils of curling gases, was the face of my mother, the long-lost Harriet.

Except for a slight darkening of the end of her nose, she looked exactly as she had in all the photos I had ever seen.

Fortunately, her eyes were closed.

She had a tiny smile on her lips-that was the first thing I noticed-and her skin was as pale as that of any fairy-tale ice princess.

It was like coming face-to-face with an image of my older self in a frosty mirror.

I was shaken with a shiver.

"Mother," I whispered. "It's me-Flavia."

She did not respond, of course, but it had been necessary to speak to her nonetheless.

Something slipped and fell down beside her neck: a bit of solidified carbon dioxide. I had been right. They had packed her in card ice for the long trip home.

Vapors were rising from the coffin, swirling briefly in the light of the flickering candles before cascading in slow drifts to the floor to form an ankle-deep mist.

I touched her face with my forefinger. She was cold.

How easy it is to say that, and yet so difficult to do.

I became aware that my emotions were writhing inside me like snakes in a pit.

Some part of me of which I was not in control made me bend over and kiss her lips.

They were hard and as dry as parchment.

"Get on with it, Flavia," I was telling myself. "You haven't a lot of time."

I needed to know at the outset if there was any warmth-any heartbeat. There wouldn't be, of course, but I had to be sure. Every experiment must start with some basic given.

Harriet was still dressed in the climbing gear in which she had been found, with an outer coat of tan-colored gabardine that was already beginning to thaw, or at least to soften a bit from the heat of the candles.

I unfastened a stiff button on her breast and worked a hand inside, feeling for her heart.

As always, I had that brief irrational fear that I've had before with corpses: the feeling that the dead person is going to leap up suddenly, shout "Boo!," and seize one's hand in a deadly grip of ice.

Nothing of the sort happened, of course.

What did happen was that, among what felt like layered wool and silk and cotton, my fingers came into contact with something more substantial than fabric.

I moved my hand as gently as possible. Whatever was tucked inside Harriet's clothing felt somewhat damp from the card ice, and brittle.

I seized it with the scissors of my first and second fingers and slowly worked it out and into the light: a large oilcloth wallet. It was as rigid as frozen fish skin.

I opened it with great care, but even so, several large flakes peeled off and fell away onto Harriet's breast.

Inside was a single sheet of grayish musty paper, water-stained and folded into four.

My hands trembled as I flattened it out and read the penciled words: This is the last will and testament of Harriet de Luce.

I hereby give, devise, and bequeath to my- Bang!

I nearly leaped out of my hide.

A thunderous knock at the door was followed by another and another and yet another: Bang! Bang! Bang! Bang!

My immediate thought was that the noise would waken Father, whose bedroom was next door to Harriet's boudoir. Or had Dogger, perhaps, given Father something to make him sleep?

"Who is it?" I called, my voice shaky in the sudden silence.

"It's Lena," came the hissed reply, muffled by the heavy paneling. "Unlock this door and let me in."

I was too shocked to reply. Here I was standing over an open coffin, nearly nose-to-nose with my mother's body, her last will and testament shaking in my hand- It was like a fevered nightmare.

"Flavia!"

"Yes?" It was all I could think of.

"Open this door at once."

Sometimes a very great shock has the effect of slowing down time, and this is exactly what happened. Almost as if disembodied, I watched myself shove the will into the wallet, drop it into the coal scuttle, close the zinc flap of the inner coffin, grab and replace the wooden lid from where I had leaned it against the wall, drape it with the black pall, shove the coal scuttle under and behind one of the heavy velvet hangings, turn the key, and open the door, all in slow motion.

"What are you doing?" Lena demanded. "Why did you have this door locked?"

As if I hadn't heard, I sank to my knees on the carved prie-dieu that had been provided for those who might wish to offer their prayers for the repose of Harriet's soul. I hoped that it would look as if I had been there all along.

"What are you doing?" she repeated.

"Praying for my mother," I said, after a long-enough pause.

I crossed myself and got to my feet. "What is it, Lena?" I asked. "What's the matter?"

One way of getting an immediate upper hand in a pinch is, as I have mentioned, to make use of an adult's name.

"You frightened me," I added.

Another way is to squeeze in an accusation-even a veiled one-before the other person has a chance to say a word.

"I thought I smelled smoke," she said. "It seemed to be coming from here."

"It's the candles," I said immediately. "They're awfully hot-and there are so many of them. With these heavy hangings-" I waved my hand vaguely. "And with all the windows shut-"

"I suppose," she said, sounding somewhat skeptical, but having a good look round the room nevertheless.

From where we stood near the door, everything appeared to be in order, every detail as it had been before I began.

It was at that instant that my supersensitive hearing registered a new sound in the room.

Drip.

Drip.

It was agonizingly slow, but as evident to my ears as a series of cannon shots.

Surely Lena must be able to hear it.

"So everything is all right, then?" she asked.

I gave her a sad nod.

"Very well," she said, but she made no move to leave. Rather, she looked slowly round the room as if satisfying herself that no stranger's ears were listening, although there might have been armies of eavesdroppers lurking behind the vast black velvet hangings.

"You will recall that I told you I was going to confide in you, Flavia. That I was going to seek your assistance. We were interrupted when that dreadful man terrified us with his aeroplane."

"Tristram Tallis," I said.

"Yes."

Drip!

Drip!

I knew at once where the sound was coming from. The card ice was melting and drops of water were falling to the oaken floor of Harriet's boudoir.

"I told you, did I not, that Undine requires a very particular kind of handling."

"Yes," I said.

"A very special kind of handling."

The candles closest to her face guttered in the peculiar hissing of her voice. A reflection danced on the floor: the merest flash of light under the catafalque.

It was water! Harriet's coffin was leaking!

I needed to get Lena out of here as quickly as possible.

"Undine likes you," she said. "She thinks you're keen. That was her own word: keen. You're very good with her."

I smiled indulgently.

"We need to talk. Not here, but somewhere where we can speak frankly without fear of interruption. Do you know the Jack O'Lantern?"

I did indeed. It was a skull-like outcropping of rock to the east of Buckshaw that overlooked the Palings, that somewhat sinister grove at a bend in the river Efon, which marked the eastern boundary of our estate. Gladys and I had ridden there on many occasions, most recently to consult with Father's old headmaster, Dr. Isaac Kissing, who was a resident of Rook's End, a nearby private institution.

"Yes," I said. "I've heard of it."

"It's at the end of Pooker's Lane," she said. "Do you know where that is?"

I nodded.

"Excellent. We shall go there tomorrow afternoon at half-three. We shall have a lovely picnic."

"After the funeral?" I asked.

"After the funeral. I shall have Mrs. Mullet put up a hamper and we shall make a day of it."

"All right," I said, anxious to get rid of the woman. At that point, I think I would have agreed to anything.

I flung open the door to speed her departure.

"Dogger!" I said. "I'm sorry! I didn't know you were there."

We had almost collided in the doorway.

"It's all right, Miss Flavia," he said. "No harm done. Mrs. Mullet wanted me to tell you that she's bringing up some cold meats. She has somehow formed the opinion that you haven't eaten today."

Lovely. Just what I needed: a nice bit of brawn to tide me over my long night's work!

"Please thank her, Dogger, but I had something in the village this afternoon. I couldn't manage another bite."

I think it was the first time in my life I had ever lied to Dogger, and I think he knew it, too.

"Very well," he said, turning away.

"If you don't want them, then I shall eat them," Lena said. I'd almost forgotten she was there.

Dogger nodded but said nothing. He watched as she walked away towards the stairs and the kitchen.

Poor Mrs. Mullet, I thought. Usually, by this time of day, she was safely home at her own hearth with Alf. She must have stayed past her time to see to the funeral meats and so forth. I must remember to take her aside later, I thought, and express my gratitude.

There was so much to be grateful for, when you stopped to think of it, in spite of all our hardships.

Dogger, for instance. This was the first time I had been alone with him since Aunt Felicity had told me his story.

How could I ever begin to thank him? How could I ever begin to make it up for what he had endured?

What can one possibly say to a person who, in saving one's father's life, has been made to endure the tortures of the damned?

I wanted to hug him, but of course I couldn't. It simply wouldn't do.

We stood there together for a few moments. I was the first to speak.

"God bless you, Dogger," I said at last.
