A man everyone wanted dead. A stair in the dark. And a verdict only you can write.
Victor Mallory built his fame ruining people. Now he's at the bottom of a lighthouse stair on a tiny island the sea seals off every night - and the five guests trapped there until the tide turns each had a reason to push.
You are Iris Kerr, the court stenographer who writes down exactly what happened. The trouble is, what happened depends on which thread you pull. The poisoned wine. The brother's debt. The lamp that died in the storm. The stranger travelling under a borrowed name.
This is an interactive mystery, and it plays fair. Every choice is a tap. Follow a lead to its end and you'll convict a killer the clues actually point to - and a different reader, pulling a different thread, will convict someone else, just as fairly. Four suspects. Four complete, deducible solutions. Read it once, then go back and accuse someone new.
Who killed Victor Mallory? That's not for the author to say. It's for you.
