Noir fiction often has tested barriers and taboos. This Lew Archer novel is in that tradition in that it doesn't break any taboos, but it does hint at it. If THE CHILL were written today, I think it would have been a bit more direct.
As with many Lew Archer cases, this one starts innocently enough with his being hired to find a missing newlywed who's disappeared after an encounter with a mysterious visitor. In a short period of time, he's involved in a murder case, one in which he feels a vague sense of being responsible. There are the usual twists, the usual questions of identity, the interconnection of characters which doesn't at first meet the eye.
MacDonald characters are difficult to pigeonhole into "good" or "bad" categories. The motivations often come from deeply within the psyches of the characters.
The emphasis in this story as well as most in the series is on the puzzle. There are seldom recurring characters in these novels, and little interaction other than investigative betwee Archer and the other characters. And as always, the dark corners of human nature are well probed.
Definitely highly recommended.
