Partners in Crime (Tommy & Tuppence 2)

Tommy and Tuppence Beresford were restless for adventure, so when they were asked to take over Blunt's International Detective Agency, they leapt at the chance. After their triumphant recovery of a pink pearl, intriguing cases kept on coming their way: a stabbing on Sunningdale golf course; cryptic messages in the personal columns of newspapers; and even a box of poisoned chocolates.
