This is one of a number of novels in the Desiree Shapiro Mystery Series by Selma Eichler. I found it entertaining and enjoyable, and Selma Eichler has become another author that I very much enjoy reading.
Desiree Shapiro is a New York private investigator, and in this novel she agrees to help out her ex-boyfriend, Bruce, by finding the killer of his new wife, Cheryl (poor lady was pushed in front of a subway train, though the police are ruling it an accident). The problem is, Desiree can't be certain that the killer wasn't Bruce himself, who was a scoundrel when she was dating him. It appears that the victim may have come upon some information that she should not have known, and that could very well be the reason she was killed, if indeed, it proves not to be an accident. Now Desiree must put her sleuthing skills to work and investigate Cheryl's death, and the case really has Desiree stumped.
I found Murder Can Singe Your Old Flame to be an interesting book, one that kept me intrigued and wanting to continue reading. This is only the second of Selma Eichler's books that I have read, but I will be reading more (in fact, I just started a third one and will be doing a review on that when I am finished).
If you enjoy mysteries that keep you guessing, you will enjoy this book.
