Description:
Soon after six o'clock on a warm August evening the Ariadne Inn was
packed with humanity, and it was not immediately apparent that one of
the guests at a table in the gardens was not asleep but dead! There were
mysterious elements in the cause of his death and a still greater
mystery in his previous activities. Who was this Mr. Warstock and why
had he come to the Ariadne? Inspector Waghorn breaks a gang of thieves
who have found an ingenious way to defraud the Post Office and, along
the way, murder a man by poisoning.
