No Good Deed by MJ May

Three years ago, Perry Atherton tried to play the hero. Turns out real life isn’t like the movies. Instead of saving someone’s life, his reward was head trauma and a blown-out knee. Perry’s dream of becoming an astrophysicist was obliterated along with his memories of that tragic night. Left with a poor memory, painful migraines, and a constant limp, he’s grateful for his custodial position at Maverick Insurance.
Perry can’t remember. Detective Nathanial Harmon can’t forget. The first night Nate met Perry is seared into his brain—Perry lying on his back, the colorful sequences of his Pride shirt glittering in the otherwise dark alley. Perry’s ragged breaths, swollen face, and hemorrhaging body their first introduction.
Perry and Nate’s futures are about to collide again—the instigator: a note Perry was never meant to find, let alone read. A murderer lurks in the office building Perry cleans, and a nameless employee appears to be next on their hit list.
Perry’s not sure he’s ready to get involved again. He tried to play Good Samaritan before with horrific consequences. But the note screaming murder won’t let his conscience remain quiet and convinces him to tempt the phrase “No good deed . . .” again.
