A summer holiday by the sea beckons for the Jinks family, and of course Ben is bringing Stinky, his genius of a hamster, along with him. But a trip to the local museum uncovers the mystery of long-lost stolen diamonds and a map. Does 'X' really mark the spot? And can Stinky and Ben find the hidden loot before the crooks track it down?

The fifth in the acclaimed STINKY AND JINKS series has all the hallmark hilarity, warmth and exciting adventure that readers have come to expect from Dave Lowe.
