The boys are working part-time at Amigos Press, run by the smart but clumsy Beefy Tremayne. He’s just taken receipt of the potentially explosive memoirs of Madeline Bainbridge, an actress from Hollywood’s Golden era, who might or might not have been a witch. When the Amigos offices are burned down, the memoirs stolen and Bainbridge’s films snatched from a TV studio next door, it’s up to the boys to get to the bottom of things. Starting with a bang, this has a terrific pace and is a real page-turner, with some great supporting characters and a nostalgic appreciation for old Hollywood. The boys interplay was excellent, the plot was watertight and some of the set pieces were inspired. This is great fun and a terrific read, very highly recommended.

The format B version, which is the one I have. The same story, a completely different selling point. I like both, to be honest, but my trusty paperback was the first time I got a chance to read the book and so it remains my favourite.
