The Guardian - Last Chance Heroes, #5

Secret admirer or stalker? The last thing Sara Vance needs is a disruption of her well ordered life. Sara is the new mayor of her small town, a woman steeped in tradition and obligation. So someone stole her underwear off the clothesline. It was a childish prank, nothing more. Wasn't it? The appearance of an old boyfriend is much more disturbing than any prank. Dante Mangino is a temporary member of the police force as a favor for his cousin, the chief.
It's boring duty, and it's not long before he's regretting his decision to help. He had to cut his hair for this job; he wears a boring suit and tie. Things get much more interesting when he's called upon to investigate Sara's panty thief. She's the one that got away, half a lifetime ago. When it appears that the prank might be more serious than anyone suspected, Dante makes it his mission to protect Sara.
Protection is his job, his calling. He failed once before; he won't fail again.
