Agatha Christie's ingenious mystery thriller, reissued with a striking new cover designed to appeal to the latest generation of Agatha Christie fans and book lovers.

At first the interruption to the boredom of Sherlock Holmes seems to have little to do with crime. A governess, whose father vanished ten years ago and who has been receiving money each year, now needs an escort to meet her unknown benefactor. But before the night is over, murder has occurred.

Philip Marlowe's on a case: his client wants him to recover a rare gold coin called a Brasher Doubloon, missing from her late husband's collection. It becomes complicated when Marlowe finds that everyone who handles the coin suffers a run of very bad luck: they always end up dead.

When Holmes and Watson receive a cipher from one of Moriarty's henchmen warning of dark doings at a manor house, they find themselves on the trail of a murderer. Almost immediately, they are on their way to Sussex where they discover a corpse with its head blown to pieces. But all is not as it seems. For the origins of this case lie in America.
