Never a Gentleman. Hunt Club, #5

Victor Knight has never been able to juggle his work and love life to anyone's satisfaction. A hardworking investment banker in London, he's obsessed with maintaining his clients' privacy and profits, and cannot understand why those same clients are withdrawing funds when he's making them a good profit. When a dull evening supper at the Hunt Club ends in a blunt invitation to have sex with the Earl of Beecroft, he welcomes the distraction on the proviso they never discuss his business affairs.
Daniel Wellham, the Earl of Beecroft, has long admired Victor Knight. He even understands and admires the banker's preoccupation with work. Their night together is everything he hoped it would be and while he longs for permanence, his secret life as a spy means he can never reveal too much of his own history. Unfortunately, when he realizes that all is not right in Victor's life, those promises he made to keep his nose out of the banker's business means he cannot offer to help or explain that his latest mission might take him away forever.
How can love and trust be possible when duty and responsibility prevent total honesty?
