Toxillicide!â
âToxillicide?â I repeated. Heâd let the name of the poison slip. What was it? Iâd never heard of it.
Winter nudged me urgently. âBoges, look,â she whispered. âThereâs someone up there!â Moonlight streamed onto the floor. Someone had opened the trapdoor. And that someone was up there right now, listening to every word.
A bodyguard? Rathbone?
I braced myself for Sligoâs accomplice to show himself. Instead, the moonlight vanished. Darkness fell as the trapdoor closed tightly again.
I jumped at the sound of Sligo shouting at someone. I couldnât make out what he was saying through the crackly speaker. Did he have someone in there with him?
A thought struck me. He was talking to Calâhe was right there on the other side of the wall! Had he been in there all along? I shone my torch on my friendsâ worried faces.
âWe need to get into the other chamber!â I said, grabbing a piece of metal from the broken TV, jamming it into the tiny slit where the door had closed. I tried to use it like a crowbar, but it was no good. It bent under the pressure in seconds.
Ryan and Winter both grabbed with their fingers, trying to get a grip on the door.
âWhatever youâre doing out there,â Sligo roared, his voice deafening through the speaker, âstop immediately. Donât do something youâll regret! Iâll kill him!â
I froze at these words and heard Winterâs suppressed sob. But we had to do something to save our friend. I pressed the round depression in the wall nearby. Maybe if we could dismantle the mechanism, we might be able to get the wall to move again. But what could I use?
Suddenly I knew just what would do it. âWhereâs my bag?â I whispered.
âHere,â said Winter, picking it up from the corner and handing it to me.
I swept my good hand through the pocket in the back, trying to find the tin capsule.
I pulled it out and cracked it open with my fingers. Out fell my latest toy. Unfinished, but that didnât matter right now.
âWhatâs that? A beetle?â asked Ryan, shining his torch on it.
âMeet Atom Ant,â I whispered. âIt canât walk yet, but see its abdomen? Filled with explosives.â
I placed the miniature grenade into the depression in the wall and pulled the tiny fangs out to activate it.
âQuick!â I said, grabbing my friends and pushing them down.
Winterâs eyes widened in shock. âYouâre going to blow us all up!â
âHope not.â I tried to sound confident. âCover your ears!â
The Ant exploded in a blinding flash, spraying us with minced concrete and rock.
Sligo yelled something from the other side of the wall but I couldnât make it out.
I bolted over to the door and pulled back with everything I had. Ryan and Winter jumped up to help me, shaking dirt and debris from their hair. Shooting pains pulsed up my injured arm as centimetre by centimetre, the wall shifted.
âIâm warning you!â Sligo yelled.
Finally the door opened enough for us to see into the other, dimly lit, chamber.
Winter squeezed through the gap sideways and ran in.
I barely had time to register the size of the other chamber, except to notice it was twice as big as the dungeon weâd been held in. Rubbish littered the corners, there were two makeshift beds, dirty rugs, some buckets, shelves, dirty towels and a couple of lanterns. A tripod for the video camera, a desk, two widescreen laptopsâone showing some type of architectural plans,the other flashing green like a sonar screen. And two red-and-white striped mugs, same as the one weâd seen at the lighthouse.
âCal!â Winter screamed, skidding to a halt almost instantly.
I looked left. Cal lay slumped in Sligoâs arms, hanging like a dead weight. Shocked, I saw the shackle that bolted his ankle to the stone wall.
But worse than
