Penetration Test by Clancy Nacht

For years, brainy, charming FBI techie Sam Dupre has helped Hunter Walsh and Cal Riggs solve their cases. He’s also become one of Hunter’s closest friends, someone Hunter counts on when things get tough.
After the events of “False Flag,” Riggs is no longer the agency’s golden boy, so when Hunter suspects a gay couple has been murdered in a hate crime in an exclusive gated community in Olympia, he takes the tip to Sam instead. While Riggs and Hunter contend with workplace politics and Riggs’s recovery, Sam Dupre drives the case forward, even securing a partner for his undercover field work: handsome, popular recent transfer Rob Crawford.

Crawford’s a seasoned field agent who doesn’t bat an eye at posing as a gay married couple, but Sam can’t help feeling like Crawford’s mocking him. They rub each other in all the wrong ways in private even as they pretend to be a doting married couple in front of the neighbors…at least, until they start rubbing each other the right way.
Sam’s dysphoria-and his HIV status-has held him back, but as he bonds with Crawford, he starts to feel seen for who he truly is. Surrounded by mystery and danger, now is not the time to blur professional lines, but how can Sam help himself?
