Gumshoe Books' first Book of the Month is not a book!
John Finnemore's The Researcher's First Murder is a puzzle box of 100 postcards. Each postcard has two sides - the image on one side, and the text on the other.
There is a murder mystery story hidden in the postcards, but you have to figure it out yourself by putting all the cards in the correct order. It will be fiendishly difficult to solve, a great challenge for all the serious puzzlers out there.
Indeed, if you are the first to solve the puzzle correctly before midnight GMT on Friday 28th February 2025, you are eligible to win a £1000 cash prize.
John Finnemore is the genius behind Radio 4's Cabin Pressure and John Finnemore's Souvenir Programme, and he famously solved the orginal Cain's Jawbone puzzle during the lockdown.
This is also available as part of a Cain's Jawbone Bundle with free shipping:
