Everyone who has used a lock will recognise the antics described in this book. There is a lesson behind nearly every story – usually that it’s best to apply common sense to the problem faced when locking up or down. But you can’t read it in public. Your snorts of suppressed laughter, usually when reading about a manoeuvre you were involved in, will attract attention. An ideal bunk-side book, or for home by a roaring fire in winter. PW
