His Irish Detective by Summer Devon

Colm Kelly, a popular constable, is happy to be a big fish in his little pond of an Irish village—until his secret sin is revealed by his best friend. Overnight, his happy life is ruined. He loses his job, and even his family, and flees to England.

Colm might get another chance in London as an inquiry agent. His first job: watch the honorable Q.R. Marrill, the next heir apparent to a fortune, who lives under a cloud of family deaths. It’s unclear if Marrill is the perpetrator or the next victim of a killer who has struck before. Colm must discover the truth, and the best way to do that is to act as the man’s valet, a menial job Colm is ill-suited for. Worse, the young gentleman is nothing like Colm’s image of an aristocrat and more like his idea of perfection. He has no desire to ruin his life again with unwelcome passion.

The bookish Quade Marrill, fourth son of a wealthy landowner, has led a contented solitary life in London separate from his family. But as his family members die one by one, he becomes heir. Even as he mourns his dead brothers, uncle, and cousin, he wonders if the deaths were more than bad luck. Someone sinister might be on the hunt, and he would be the main suspect The only way to discover the truth is to allow the alarmingly intrusive Colm Kelly into his life.
