Going Deep (Fitting In) (Volume 4)

Gray, Jack, and Mason are back. Their threeway relationship keeps growing stronger, and Gray 's feelings for his partners run deeper than he ever thought possible. While he’s learned to be romantic at home, at work, he’s still a big tough cop that nobody wants to cross. When the murders of several young prostitutes falls to him to solve, and he has no suspects and no motive, his confidence takes a hit. Every dead end, every day that goes by, adds to the urgency he feels to find the murderer.
Gray desperately needs a break, with the case and for himself. He excels at taking care of both his men, in bed and out, but when it comes to accepting comfort in return, he shuts down, even with everything at work going to hell. Jack and Mason want him to take a vacation when the case ends, but Gray knows he sucks at down time unless it’s spent in bed.
With his case weighing on him and his partners trying their best to help, Gray is going to have to figure out how a high-handed man like himself can let go.
