Up in Flames — Linda S. Bingham

Mystery. Houston arson investigator John Bolt isn't looking for love. He is hot on the trail of a serial firebug who has blazed a name for himself in a small New England college town. But a bumpy flight brings Mary Yates, an actress in deaf theatre, into Bolt's life. Together they search for motives in a case that turns from matches into murder, and in the process, sets their hearts aflame.
