Sometimes it's just not meant to be. Have you ever tried multiple books written by the same author and had none of them "grab" you? That's what's happened to me with Timothy Williams. This is the second book he's written that I've read (from two different series), and both just fell flat.

In Persona Non Grata, the reason for my disinterest lies almost entirely in the lap of Commissario Piero Trotti. He is a thoroughly unlikable person. The only character that I did like was Ciuffi. She's good at her job, she works hard, and she's sick and tired of being treated like a fourth-class citizen by the men in her department. She has some very valid complaints which she brings to Trotti's attention from time to time. She admires and respects him for the quality of his work and would love to have him as her mentor, but Trotti very plainly has no intention of listening to anything she has to say unless it directly relates to the case they're investigating-- and sometimes not even then.

As always, your mileage may certainly vary-- and I hope it does-- but for me, I think I've learned my lesson. I'll refrain from reading any more of this author's books. He undoubtedly enjoys so-so reviews just as much as I (don't) enjoy writing them. ( )
