Harlequin intrigue #2182

"On leave from the military, Dillen Bullard confronts his estranged father's death--and is sure it was no accident, as the cops claim. It was murder. Unfortunately for the troubled army ranger, a woman from his past, the very rich Liz Hayes, compounds the mystery. Though he once thoroughly disliked the 'princess,' now he'll investigate with her despite her crucial memory loss. Before long, he's saving her life. And risking his heart." -- Page [4] cover
