The Old Man in the Corner (Unabridged‪)‬

In a genteel ABC teashop on the Norfolk Road, Miss Polly Burton (of the Evening Observer) spends her lunch breaks listening to a mysterious old man, as he unravels cases of murder, blackmail, theft, and deceit that have filled the headlines, and baffled police and public alike. But to him, they are not "mysteries" at all - for Polly's brilliant but eccentric companion, "There is no such thing as a mystery in connection with any crime, provided intelligence is brought to bear upon its investigation."  

A collection of classic tales in the Sherlock Holmes vein, from the creator of the Scarlet Pimpernel.
