Arsenic and Old Lies by Benedict Brown

The last book was left on a cliffhanger. Marius and Bella he just returned from solving another crime and Marius had discovered the body of someone Bella loved in his living room. Now, he has to figure out what to do next. And that is to apparently ignore the body completely (an amatuer detective who follows police orders? I'm not sure how to process this.) In fact, this particular murder isn't really touched on again until the end of the story. 

Instead, Marious, needing inspiration to get around his writer's block, decides to investigate a cold case. In particular, he chooses the case of Felicity Mortimer who was accused of poisoning her much older, infirm husband. The case interests him because the evidence seemed so thin but the judge was so overly irate in his sentencing.

While Marious does some investigating on his own, Bella does eventually joins his efforts. There will be two more murders before the two can finally figure out what is going on, and what actually happened fifteen years ago.

The ending felt a bit rushed to me but the suspects were certainly a group of characters who, while maybe not fully fleshed out, were entertaining.
