Bookshop owner Gemma Doyle heads to London for a wedding, but when a body is found in connection with a rare book, Gemma sets out to sleuth the slaying in bestselling author Vicki Delany's tenth Sherlock Holmes Bookshop mystery.

Gemma Doyle and her friends have packed their bags and headed to London for her sister Pippa’s wedding. Waiting for her in the hotel lobby is none other than Gemma’s ex-husband, Paul Erikson. Paul has a rare book he wants her to see—calling it “the real deal”—so Gemma agrees to meet him at their old shop, Trafalgar Fine Books, the following day. But when Gemma arrives, accompanied by Grant, a rare book dealer, they find Paul dead in his office.

Paul had been down on his luck, but Gemma never expected this. Had he borrowed money from people he shouldn’t have? And where is the valuable book he was so anxious for Gemma to see? It’s nowhere to be found in the shop. Because of their previous relationship, Gemma feels she owes something to Paul and vows to find his killer.

As Gemma and her best friend Jayne Wilson follow Paul’s trail of friends, enemies, clients, and ex-lovers through London to Yorkshire, she realizes the puzzle of Paul’s last days is more twisted than she originally thought.

This mystery is anything but elementary, and Gemma and Jayne have to use all their wit to get to the bottom of it before their time in London—or in life—is over.

Vicki Delany began her writing career as a Sunday writer: a single mother of three high-spirited daughters with a full-time job as a computer programmer. The years passed, as they tend to do, and the three daughters, somewhat hesitantly, flew the coop, leaving Vicki more time to devote to her writing. She was able to write three novels of suspense, set in Ontario, two of which, Scare the Light Away and Burden of Memory, were published to critical acclaim by Poisoned Pen Press of Scottsdale, Arizona. In 2007, In the Shadow of the Glacier, the first book in a police procedural series set in the British Columbia Interior was published. Born in Winnipeg, Manitoba, Vicki was raised mostly in Ontario. Vicki majored in modern history at Carleton, her interest more in the lives of ordinary women and men and the circumstances of their times than ‘big men’ and their wars. It was on a canoeing trip in Algonquin Park that Vicki, realizing that she was doing for fun what people in the past would have considered a hardship, told her trip mates stories about the incredible difficulties people endured in their attempts to get to the Klondike in search of gold, and the idea for a series of Klondike Gold Rush mysteries was set.
