Codewords have been one of The Daily Telegraph's most successful puzzles since their introduction to the paper in summer 2003, and here we are proud to present another in the popular series of Codewords books. The principle is simple: the unsolved grid shows squares containing numbers, each of which corresponds to a letter of the alphabet. Between two and five solved letters are given, and the remainder must be discovered through a combination of logic and word power. This collection contains 150 brand new puzzles. Can you crack the code?
