    Before you open the case

    What am I trying to solve?

    A murder has taken place, and the answer is hidden in a hotel guest register. Your challenge is to use 20 clues to work out which entry belongs to the killer.

    How do I get started?

    Start with a clue and check it against the register. Cross off every stay that cannot match, then move to the next clue. Each round leaves fewer possibilities.

    How big is the investigation?

    You have 10,013 hotel stays to investigate and 20 clues to narrow them down.

    What should I look for in the records?

    Look closely at the guest names, room numbers and lengths of stay. Each clue tells you which details matter for that part of the investigation.

    Will I be marking the pages?

    Yes - crossing off entries is part of the game. Keep a pencil or highlighter beside you so you can record each elimination.

    Am I reading a mystery or solving one?

    You are solving it. The story sets the scene; the clues and register give you the material to investigate for yourself.

    Can I pick it up and put it down?

    Absolutely. There is no timer. Your markings show what you have ruled out, so you can return to the case at your own pace.

    What changes in Volume 2?

    The Perfect Alibi switches the challenge to alibi deduction: compare 14 statements and movements across 96 rooms to uncover one liar.

    What do I get with the bundle?

    The bundle contains both books: Lily Let The Killer In and The Perfect Alibi.
