'A page-turning cosy crime delight, with a fearless heroine and a twisty mystery at its heart, full of humour, drama, revelations and romance' – KATIE MARSH

London, 1932. A young maid steps onto a train… and disappears. Her desperate family writes to the only person they can think of to help: Sherlock Holmes. A shame then, that Mr Holmes isn’t real. But then, from a basement beneath 221b Baker Street, someone replies…

Harriet White knows responding to the maid’s family could land her in hot water, but she’s no stranger to trouble. It was refusing to cow to her over-familiar boss that saw her demoted to the postal department of their Baker Street head office in the first place. Her new job is to work through the mountain of correspondence addressed to the street’s most famous resident. But when this letter catches her eye, she knows she must do something to help the missing girl.

Harriet decides to act as Holmes’ new assistant, armed with only her love of Conan Doyle’s stories to guide her. But can she solve the case of the missing maid? Or does she risk losing her job – or much, much more – in the process?

The link to Sherlock Holmes intrigued me as I didn't know that this was based on the fact that someone was actually employed at the Building Society to answer letters sent to Sherlock Holmes.
