His Spy at Night - Spy Games, #3

For love of the game. You win some, you lose some. Intelligence officer Marlies Wiersma plays hard and loves harder-sometimes with disastrous results. After falling for a man who wasn't who he pretended to be, Lies is anxious to prove to her boss that she won't make the same mistake twice. She accepts an assignment which pits her against a charming crime lord-and alongside a diplomat with no patience for spy games, particularly feminine ones.
Keep your friends close and your enemies closer. When a national security threat results in Trade Commissioner Harry Jordan harboring a spy in his embassy office, his instincts scream that Lies Wiersma is a woman not to be trusted. The two of them are supposed to be on the same team, but Lies is a little too good at these games for Harry's personal comfort. He's been burned by a woman before. Harry's reluctance to play along proves to be too much temptation for fun-loving Lies to resist, and once again, she finds herself in over her head with a man.
This time, however, he's exactly who he claims to be. Now Lies has to convince Harry that, no matter who she pretends to be during the day, at night she's all his.
