You might know the author of the 509 Crime Stories and the co-author of the Charlie-316 series already. This is his PI style series.
Former deputy Sam Strait has been snowbirding and comes back home to discover a dead body in his home. He decides to investigate himself and ends up getting involved with a tough female bodybuilder, several thugs and more.
Sam is a fun character. He might be an ex-cop, he's not the tough guy you might expect. His fighting prowess puts him pretty much into cozy territory. He's also really more of an amateur sleuth than an unlicensed PI type. His rules of living are amusing, one of which is to never go where he cannot wear flip-flops, hence the title of the series.
The story has some nice pacing. Not too fast, not to slow. It feels like an entertaining stroll hand in hand with Sam. There seem to be a few somewhat open plot points in here, but overall a nice story.
Will be back for more.
