The Marlow Murder Club by Robert Thorogood

 Judith Potts is convinced that her next-door neighbor, Stefan, was murdered, although the police (including DS Tanika Malik) believe it was suicide.  Judith then decides to investigate Stefan's death herself. In the course of her amateur investigation she meets Becks, the vicar's wife, and Suzie, a local dog walker. The trio are a humorous bunch who develop a real friendship, yet their skills and ingenuity are put to the test when they realize that a serial killer is on the loose. The Marlow Murder Club is a great addition to the cozy mystery genre. For those who enjoy M.C. Beaton and the Thursday Murder Club series.  I cannot wait for the next book!
