Chelsea Mansions by Barry Maitland

After visiting the Chelsea Flower Show, American tourist Nancy Haynes is pushed in front of a bus and killed. With cameras all around London, DCI David Brock and his colleague DI Kathy Kolla are able to trace the movements of the murderer right after the crime. But who would want Nancy dead and would go to the trouble of committing the crime while she was on vacation? Then wealthy Russian expat Mikhail Moszynski is found stabbed to death near his home, which is near the hotel at which Nancy was staying. This leads Brock and Kathy to wonder if the cases are connected. Kathy delves into the pasts and lives of both Nancy and Moszynski in order to solve both cases. Chelsea Mansions is the latest book in the Brock/Kolla series and would appeal to people who like complex police procedurals such as Peter Robinson, Deborah Crombie, Peter James, and Elena Forbes.
