Tea and Antipathy (Damien Murphy Pet Sitting and Murder Investigations #1)
Meredith Spies

Ever since I arrived, people have been dropping dead and my new friend seems to be right in the thick of things. Mrs. Witte is a sweet older lady but she cannot keep herself from chasing down clues and pointing fingers at suspects, and her stepson Benjamin seems to think that’s somehow my fault.
Look, I’m just a washed up child star turned accidental pet sitter and sometimes plucky sidekick. I had nothing to do with the deaths that seem to be happening at an alarming rate, and Mrs. Witte is determined to make sure I don’t get blamed.
Benjamin, however, isn’t easily convinced. It’s all I can do to keep up with Mrs. Witte and that goofy mutt of hers, putting myself between her and whoever the Thespian Killer is, and it’s all Benjamin can to do put himself between me and clearing my name.
Tea and Antipathy is a slow burn cozy romance with an MM romance woven in through the mystery.
