Shadows of the Heart — Linda Vail

He was a man of mystery, a veritable Houdini. Nothing could keep Miles Delaney out. Not triple locks, or even electric eyes. And when Kelle O'Brien's customers began calling him to check out her specially designed security systems, that got her Irish up!

Steeling herself against his devastating sensuality, Kelle issued a challenge, daring Miles to break into her home. But when he appeared to wake her with a breathtaking midnight kiss in her bedroom, she had to admit she'd met her match. Reluctantly she agreed to be his partner. They would provide Las Vegas with the ultimate in protection. But Kelle had to wonder: Who was this man ? Where had he learned his stealthy skills? And could she devise a security system strong enough to protect her heart?
