The Baker Street Mysteries

When Harriet White rebuffs the advances of her boss at the Baker Street building society where she works, she finds herself demoted to a new position… a very unusual position. Deep in the postal department beneath the bank, she is tasked with working her way through a mountain of correspondence addressed to Baker Street’s most famous resident: Mr Sherlock Holmes.

Harriet White is no stranger to odd correspondence. Ensconced in the basement of the Baker Street building society, her job is to reply to the mail they receive on behalf of Sherlock Holmes. But while letters to the fictional sleuth may be plentiful, telegrams are rare, and so when she receives one describing the grave situation of celebrated author Philip St John, her interest is piqued. The writer describes St John as being consumed by terror, seeing ghostly apparitions on the fens, and only at ease in the company of his loyal wolfhound.

Harriet White is settling into life in the post room of the Baker Street building society. Until she discovers a letter in The Times challenging Sherlock Holmes to prove his status as the world’s greatest detective by solving an impossible mystery. The letter, signed Professor James Moriarty, advises Holmes that the crime will be committed within the next seven days. Holmes himself must deduce which crime is the correct one to investigate. Dismissing the letter as a prank – after all, Sherlock Holmes isn't real – Harry goes about her business.
