Query: Agatha Christie's PARTNERS IN CRIME

The detectives in this book are none other than Tommy and Tuppence Beresford, a lively husband-and-wife team who enjoy adventure.PARTNERS IN CRIME opens as most Tommy and Tuppence books do -- they are bored with life and crave adventure.

The Chief asks them to take over the failing detective agency and look for a mastermind criminal whose symbol is the number 16.
