Crack the Codeword 1: 48 Brain Teasing Puzzles to Improve Your Logic and Increase Your Word Power (Paperback) (ISBN-13: 9781452504438)

"I very much enjoy your codewords - the best I've found. I suffer a lot of long-distance flights and they are perfect to while away the hours between London and Sydney!" Richard

"I'm in crossword heaven. You are such a challenge but great. I am a retired teacher and my brain screams for challenge. I have at last found it. TV, etc. is no challenge, nor does it satisfy the inquiring mind. My son-in-law gave me a codeword book and they are not nearly as good as yours. Thanks so much Catherine, you are a great detective!" Felicity

"I really enjoy the challenge your puzzles give me." Chantelle
