Nearly a quarter-century after her death, Agatha Christie remains the most popular mystery writer of all time. Now, in a celebrated publishing event, fans and newcomers alike are treated to another Christie novel. Created in 1930 as a stage play and faithfully adapted by Charles Osborne, Black Coffee brings back beloved detective Hercule Poirot to exercise his "little grey cells" one more deliciously deductive time...

An urgent call from physicist Sir Claud Amory sends famed detective Hercule Poirot rushing from London to a sprawling country estate. Sir Claud fears a member of his own household wants to steal a secret formula destined for the Ministry of Defense. But Poirot arrives too late. The formula is missing. Worse, Sir Claud has been poisoned by his after-dinner coffee. Poirot soon identifies a potent brew of despair, treachery, and deception amid the mansion's occupants. Now he must find the formula and the killer...while letting no poison slip 'twix his low lips.

Adapted as a novel in 1998 by Charles Osborne
