Publisher's Synopsis
The police have finally caught the evil murderer Sir Mason Green - but at his trial, he is murdered in the dock. Forensics show he was poisoned by a dart - and Gerald's DNA is on the blowgun. Then a mysterious cat woman steals the ruby, the key to the third casket. Framed for murder, Gerald's quest for justice takes him to caverns beneath the island castle of Mont St Michel in France, locked rooms in the Vatican and the ancient hidden city of Delphi in Greece to discover the secret of the three caskets and the great power they hold.
