Well,... a few chapters into this snooze fest, you can safely unfasten them. Strange Witness turns into yet another plain framed-man-on-the-run story. There's a couple of things that were probably supposed to make it a bit special, but neither really works. Our guy is not alone on his run as he needs to protect some kid - the titular strange witness. Which could be cool in case little Greta was some sharp, witty teenager. Instead, she keeps whining and is a general nuisance to both him and the reader. The second unusual touch is our hero's profession. He is a ventriloquist, but he mainly uses his skill to entertain the brat by making her stuffed rabbit talk.
These are just some of the problems. Our hero is dull, the bad guys are as two-dimensional and stereotypical as they get (yes - the main villain is a fat owner of some fancy nightclub), the dialogues are lifeless, and the romantic angle requires all of the suspension of belief that you're willing to give.
The premise of a kid witnessing a murder is not bad at all. But the whole thing is 190 pages long, and there's no actual story development or tension build-up. Hardly a page-turner...
One just never knows with Keene. None of his stuff is terrible, and some is brilliant. I think this is the first one of his that I'm just gonna file in my memory as simply forgettable.
