Advent calendar books for adults: a 24-night mystery to solve in December
What an advent calendar book for adults is, how a 24-night mystery puzzle book works, and who it suits.
An advent calendar book for adults replaces the chocolate with a page a day. Nobody Leaves the Ice is a mystery told over 24 nights: each night has one puzzle, each answer narrows the suspects, and by Christmas Eve one name is left.
What is an advent calendar book for adults?
It is a book divided into 24 parts, one for each night from December 1 to Christmas Eve. Instead of a treat behind a door, there is something to read, solve or do. The appeal is the ritual: 10 to 40 minutes an evening that build to something by Christmas.
How a 24-night mystery works
In Nobody Leaves the Ice, two thousand fish houses go out onto a frozen Minnesota lake every December. This year the warden who keeps them safe is found on the floor of his shack, and the county calls it an accident. His granddaughter has 24 envelopes he left her, one for each night of Advent, and the permit register of every house on the ice.
- Each night: one logic puzzle, from map puzzles and word ladders to logic grids, sum grids and picture puzzles.
- Each answer completes one of the warden's clues.
- Each clue rules out suspects in a register of 2,412 names.
- Hints, answers and a register check are at the back.
Who it suits
Puzzle fans, mystery readers, couples who want something to do together in the evenings, and families of grown-ups. Every puzzle has a single answer, and there are hints at the back for a night that gets stuck.
Starting late
Each night carries its December date, but nothing breaks if you start late: catch up by doing more than one night in a sitting. It works just as well as a January mystery.
What can I put in an advent calendar for adults?
Something to do each night rather than something to eat: a puzzle, a page to read, a small task. A mystery puzzle book is a whole advent calendar in one book, with a reason to open the next night built in, because each answer narrows the suspects.
Do advent calendars go to the 24th or the 25th?
Most run from December 1 to December 24, Christmas Eve, and some add a 25th door for Christmas Day. Nobody Leaves the Ice has 24 nights, and on the last one, Christmas Eve, one name is left.
Giving it in time
For the full advent effect, give it before December 1. It is sold and shipped by Amazon, with gift options at checkout.
In short
24 nights, 24 puzzles, 2,412 suspects and one answer by Christmas Eve. See Nobody Leaves the Ice.
