ghosts!â yells Tilly, charging along the path behind us.
We stop by the swamp. The tree turns a little to face us.
âItâs completely horrible,â I say. âHow on earth can we get it out? Without being crushed to death?â
âAs I remember, the genus
Handus
can be charmed by riddles,â says Eric. âAnd jokes of course.â
âRiddles? But it hasnât even got ears!â
âJokes and riddles? I know lots of jokes,â says Tilly. âDoctor, doctor, I feel like a pair of curtains  â¦Â â
To my surprise the tree seems to relax.
âDoctor doctor, I feel like a pack of cards.â
Tilly starts again. âOne night, a butcher, a baker, and a milkman enter a haunted house. Four men come out. Who is the fourth?â And the tree faces her, concentrating intently, watching her. It seems not to notice us tiptoeing across the edge of the swamp until we have our arms linked around the trunk.
âHow about a limerick?
There was a boy called Tom, who ran away from a bomb. He went to a pub to get some grub  â¦Â
â
âOne, two, three â lift!â I hiss, and Eric and I pull, ignoring the awful squelching sound around our feet. The roots, although wide, arenât particularly long, and after three goes we actually get it out of the ground.
âQuick, weâd better run back,â says Eric, and between the three of us we try to pull it along the path. The arms are still flailing but so long as Tilly tells it riddles, it seems less aggressive, if a tree can seem less aggressive.
âIâm here, Iâm here!â shouts a voice from the mist.
âVictor?â asks Eric.
âYes, yes, canât let the poor mite drown. Hand tree eh? Very resourceful â let me help.â
Between the four of us we get back to the shore of the lake, just in time to see Jacobâs limp hand sink below the surface.
âNow!â
We shove the tree out over the water, and without Tillyâs riddles, it twists around searching for something to grab. Finding Jacob, it plucks him from the water, drags him towards the shore accompanied by his two strange jelly-ghost floats and holds him high in the air.
âBravo!â says Eric.
âResult,â coughs Jacob, throwing up a weekâs worth of sweets.
âHow very  â¦Â necessary,â says Victor.
Chapter 15
The tree really likes Jacob. It wonât let him go even with Tilly standing there telling it riddles and laughing at her own jokes.
âHelp! Help!â Jacob shouts, caught struggling in the branches like a huge purple beetle in a spiderâs web.
Iâm so out of breath I can only stand and stare and gulp air.
âOh for goodnessâ sake,â says Tilly. She pokes the tree in the joints between the branches and the trunk. âLet go of him,â she orders in her best dog-trainer voice.
The tree squeaks, releases Jacob and rolls its branches over the trunk protectively, as if Tilly had actually tickled it in its armpits.
The moment it does, we rush out of the bell tower, abandoning the flailing tree on the side of the Lilac Lake.
I glance back at the writhing branches dripping purple liquid onto the floor, and shudder. I almost feel sorry for it â and then I remember Vile Lucy and catch up with the others.
âSo how are we going to get home?â I ask as we stumble back in the half-light towards the broken harbour. âThe boatâs not due back for hours. I mean, Tilly, you dragged us here â you must have had a plan.â
We stop in the graveyard next to the harbour.
Tilly flicks her hair over her shoulder. âPlan? I thought you had a plan, Tom. You were here to look after me. I assumed youâd thought about it.â
I decide not to answer her. Beside her are what must be Flora Rose and Billy. Theyâre almost visible as a result of the lilac goo. Billyâs quite little, wearing a cap,
