Black Girl, White Girl — Patricia Moyes

When an old friend from the newly independent Caribbean nation of Tampica turns up in London afraid for her life, claiming the island has become a haven for the traffic of cocaine --"white girl" in island parlance--Henry and Emmy Tibbett agree to help her get the goods on the Mafia-corrupted local officials. But amid the deceptive calm of a lush tropic resort, they soon discover that they can trust no one, because nothing is what it appears to be and the only reality is that each of them is in the gravest danger.

With Dead Men Don't Ski, published by Holt in 1959, Patricia Moyes introduced readers to Henry Tibbett, Chief Superintendent of Scotland Yard, and his indefatigable wife, Emmy. Now, with Black Girl, White Girl, Moyes offers her eighteenth mystery with this much-loved couple, who continue to prove that, in the war against the wicked, two minds are better than one.
