Zarina Left a List

One new case a day. Same method as the books: eliminate names, dig into the files that remain, and prove who did it. Free on the App Store and Google Play.

Three stages. One killer.

Each Zarina Files book is a printed investigation. You do the work in order.

  1. 01

    The list

    Zarina gives you every possible name. Using her clues, you eliminate suspects until only a short pool is left.

  2. 02

    The deep dive

    For the names still in, you dig into denser evidence — records, then files — until the pool can’t shrink without a real reason.

  3. 03

    The proof

    When you’re done, one name should still fit. Check it behind the solution seal with the key in your copy.
