This volume in Simon Shuker's challenging Code-Cracker series returns to the format of alternating single and double-letter starter words. An additional "hint letter" is included for each puzzle at the start of the solution pages, for those occasions where you find it hard to get started. Happy puzzling! Shipping: $8 per book.
