His Lordship's Secret by Samantha SoRelle

London 1818 Alfred Pennington, the Earl of Crawford, knows someone wants him dead. An illicit boxing match seems the perfect opportunity to hire a champion fighter to watch his back, but Alfie is shocked to recognize the beaten and bloody challenger as his childhood friend, Dominick, one of the few people who knows the truth about Alfie’s past. Life has been hard for Dominick, so he can’t believe his luck when Alfie—now with fine manners and a fancy title—offers him a chance to escape the slums in order to catch a potential killer. That’s difficult enough, but not falling in love with the refined, confident man his friend has become may prove trickier still. The investigation draws the two men closer than ever, but it becomes clear that their years apart may prove too much to overcome. As the danger mounts, can they find their way through the past to a future together? Or will hidden secrets cost them their happiness… and their lives? His Lordship's Secret is the first novel in the His Lordship's Mysteries series.
