Teen twins Rich and Jade Chance are finally on vacation in Venice with their father -- or so they think. In reality, the British government has sent master spy John Chance to keep tabs on a Swiss banker who is desperately trying to escape from the Tiger, a ruthless criminal mastermind.

In no time, the banker is captured by the Tiger's thugs and taken to a remote Scottish castle -- along with Rich! Now it's up to Jade and Chance to rescue them both. Will they be able to stop the Tiger before Rich's time runs out?

Fast-paced and thrilling, this page-turning adventure is an exciting follow-up to Jack Higgins' brilliant first foray into young adult fiction, which Publishers Weekly called "a sure-fire hit."
