A Lighthouse for the Lonely Heart: An Oregon Coast Mystery - A Garrison Gage Mystery, #5

They find his body at the bottom of Heceta Head Lighthouse-Ed Boone, a longtime volunteer who commits suicide rather than see his grim diagnosis to its bitter end. The strangeness of the old man's death makes the local news, but Garrison Gage thinks little of it until the famous Nora West sneaks into town with an unsettling letter in hand. Professing he wants to go to his grave with a clear conscience, Ed claims to be Nora's biological father.
But the revelation stirs up all kinds of complicated emotions for the talented but troubled musician, who hires Gage to find out the truth. Yet the truth may be a lot more disturbing - and dangerous - than either of them expect.
