Elementary, She Read

A "fast, fun" cozy mystery "full of Sherlockian lore"—set at a Cape Cod bookshop run by a "heroine as observant as the Great Detective himself"! When murder pays a visit to Sherlock Holmes Bookshop and Emporium, Gemma Doyle must use the powers of deduction to find the killer—and clear her own name.

Gemma Doyle, a transplanted Englishwoman, has returned to the quaint town of West London on Cape Cod to manage her Great Uncle Arthur's Sherlock Holmes Bookshop and Emporium. The shop—located at 222 Baker Street—specializes in the Holmes canon and pastiche, and is also home to Moriarty the cat. When Gemma finds a rare and potentially valuable magazine containing the first Sherlock Homes story hidden in the bookshop, she and her friend Jayne (who runs the adjoining Mrs. Hudson's Tea Room) set off to find the owner, only to stumble upon a dead body.

Gemma is the police's first suspect, so she puts her consummate powers of deduction to work to clear her name, investigating a handsome rare books expert, the dead woman's suspiciously unmoved son, and a whole family of greedy characters desperate to cash in on their inheritance. But when Gemma and Jayne accidentally place themselves at a second murder scene, it's a race to uncover the truth before the detectives lock them up for good.
