Skin in the Game: Romantic suspense
Tai Randolph likes dead people. As a tour guide, she enjoys recounting their histories, weaving stories that are sometimes more entertaining than true. But when she discovers a young woman's murdered corpse in her estranged father's driveway, she decides that dead people -- and dads -- are more trouble than they're worth.
Complicating matters further is Trey Seaver, field agent for Phoenix, an exclusive corporate security firm where her father now works as an industrial psychologist. A former patient of her father's, Trey is good-looking and smart, but still recovering from the car accident that left him psychologically damaged -- and strangely gifted. He’s fearless, focused, and amazingly accurate at lie detection -- 87% of the time anyway -- but he's also rule-obsessed and emotionally inflexible. And he's not thrilled to have an unpredictable amateur “detecting” on his turf.
The Atlanta police soon arrest the victim’s meth-dealing ex-boyfriend for the murder, but Tai
suspects the real truth ISN'T the official version both Phoenix and the authorities are enthusiastically promoting. After all, bodies don’t just randomly appear in one's front yard -- they show up for a reason. She wants to believe her father isn't a murderer, but knows she can't give their relationship a fair shot until she learns the whole truth. Surreptitiously. Because facts don't lie, and with an oddly attractive human lie detector dogging her every move, neither can she, no matter what secret she may inadvertently dig up.
This has every contrivance in the book. "concealing the true story" "car accident gives surprising gifts" "mis matched deterctives".
You've glossed over the lack of story with gimmicks. There's no antagonist, unless you think one of the two main characters serves that function.
