The Scottish Duke — Ryan Field

In this installment of The Rainbow Detective Agency, Blair and Proctor's passionate relationship has moved forward to the point where they begin a small family and don't even realize it. And that's because they're busy trying to solve the case of a well-known gay romance author, E. Q. Montana, who was so obsessed with Proctor he lined the walls of his unkempt West Hollywood apartment with Proctor's photos.
But E. Q. Montana wasn't just any best-selling gay romance author. E. Q. had a few deep dark secrets and enemies of his own that Proctor and Blair have to figure out, one of which has to do with The Scottish Duke of Huntley. It's a peculiar case of dangerous literary subterfuge, with sudden twists and vicious, ambitious authors, that has them both stumped emotionally and intellectually, and in the end Proctor's worst nightmare comes true.
