A puzzle book nobody else has.
Find the Heir is a logic puzzle you print and solve with a pen, or solve here on screen. You get a county register of thousands of births and a bundle of memoranda, letters from the solicitors about the one person who inherits. Strike out everyone the letters rule out, and exactly one name is left standing.
Every copy is a different puzzle, and each one is sold to one person only. So there is no answer online, and nobody can spoil yours.

How it works
- Buy a book. We take one copy out of stock and put it in your account for good. It is never sold to anyone else.
- Print it, or solve on screen. You get the PDF, and on screen your strikes are saved as you go.
- Find the one name left. The last page confirms you are right without ever naming anyone.

Every copy is its own puzzle
Most puzzle books print the same puzzles for everyone, and the answers end up online. Each Find the Heir book has its own register, its own memoranda and its own heir, and it is sold to exactly one person. Even if you ask for a refund, it is never sold again. The only way anyone learns your answer is if you tell them.
Every book is proved to have exactly one answer before it is issued, so the evening you spend on it cannot end in two names or none. How a book works, in full.
