Reminds me of S. Kaminsky;s Abe Lieberman. Fun character with a good plot.
From the back cover: It's a high price to pay for a pack of smokes when Frost interrupts his vacation to filch some of Commander Mullett's cigarettes & finds himself pressed into emergency duty.... In the next few days, Frost will deal with a blackmailer, a shifty businessman, a not-so-grieving widow, a sexual pervert or two, a crazed housewife, & a cold-blooded killer...
