A cover art comparison

Two literary thrillers about murder and psychiatry in turn-of-the-century New York City... two similar covers. (Look at the central figure.) These are the British versions.

Many reviewers have already compared the two novels because of their similarity of theme. I can't call this as strong a trend in cover art as the "headless bodice" type - seems to be more of an attempt to attract the audience of one to the other - but do you know of any other covers that resemble these? Anyone read either, or both?
