The mammoth book of puzzles - Victor Serebriakoff

This collection was compiled by Victor Serebriakov, one of the world's great puzzlemasters. It is absolutely NOT just a collection of assorted puzzles. It is a structured and graded obstacle course of quite fiendish difficulty. (Victor himself writes in the introduction that he is a 'self-confessed sadist'.) To make the task even worse there is a time allowance for each puzzle and you cannot rely entirely on genetic advantage - you have to fill in the IQ test before you start, and if you do well you will find yourself handicapped! Sounds awful, but think of the pleasure when you get them right . . . This best-ever compilation of puzzles is now back by popular demand.
