Query: Amis is way off his form and getting careless.

This noir-wannabe mystery wasn't worth what I paid for it, and I read a library copy! Amis sets up a mystery which he doesn't explain to any degree of reader satisfaction, narrates through a completely unconvincing female character, sets it in a generic American city with no sense of authenticity in any of its details... Ah, but there's a killer photo of Amis on the dust jacket. Reading our own publicity, are we? Impressed with ourselves maybe just a skitch? London Fields this one ain't. Reread Elmore Leonard instead.
