Hooked on a feline

It's summer in Mayville Heights, and Kathleen Paulson and her detective boyfriend Marcus, are eager to attend the closing concert of the local music festival. The concert is a success, but then one of the band members is discovered dead shortly after it. At first it's assumed the death is a robbery gone wrong, but Kathleen suspects foul play and she's certain that she, along with her trusty side-cats, Owen and Hercules, can help solve the murder.
