Twenty-four days. Twelve thousand names. One of them did it.
A Wyntergrave Mystery is a series of advent puzzle books written by Nell Ravensworth. Each volume is a single investigation, solved a day at a time, with nothing to download and no application to install. The solution is printed in the back of the book, where it belongs.
Readers of the first volume
There is a Postscript — the killer's own account of what was done and why, which appears nowhere in the book. It is free.
