Murder a Cappella‪,‬

In San Antonio, the Sweet Adelines International Barbershop competition starts out with a bang. Actually, two bangs as two women of a quartet singing on an outdoor stage in front of the Alamop are shot and killed. Tina, a member of the Fort Worth police department, is there, singing with the Fort Worth Flair chorus. The members of the ill-fated quartet are also members of the Flair. Tina sees two of her friends from the Flair gunned down and she vows to find the killer. Fortunately she knows the detective assigned to the case and convinces him she will be a big help since she is in the Sweet Adelines and can find more information than an outside police detective. The San Antonio police have no suspects, no leads, and the detective agrees to keep Tina in the loop if she supplies him helpful information.

The decision is made that the Flair will continue in the week-long competition. Tina is on the costume committee for the Flair.  So she has to deal with rehersals and costumes problems. She sifts through the sequined costumes and whispered gossip, desperately trying to find clues. But when another member of the Flair is murdered, it becomes clear that the killer has more on his mind than a song, and Tina may be the next victim.
