Query: Short and Sour

Short and sour, this is a story of an unconvincing suicide mystery investigated by an unconvincing woman "police" in an unconvincing Chicago. That it does not convince isn't even the main problem. The withholding of information from the reader is. We are told that of all the bodies Ms. Mike O'Hoolihan has ever seen, none has stayed with her like this one. Why? That Officer O'Hoolihan finds the reason for the suicide and doesn't share it, except for a corny reference to suicide being contagious, is downright sophomoric. No mystery here, just a good writer trying to hoodwink his reading public into thinking that he is consistently a good writer. Thanks for nothin' Mr. Amis.
