An impression is worth 100 words

Short is sweet when it comes to fiction, according to Robert Collins at the Guardian blog a couple of days ago. "Novels don't have to be long to say something — just look at A Clockwork Orange, The Great Gatsby and The Outsider, all of which barely break the 100-page barrier and fit nicely in your back pocket." I agree on these examples, which I have read, and also with One Day in the Life of Ivan Desinovich, The Old Man of the Sea, Of Mice and Men, On Chesil Beach and The Prime of Miss Jean Brodie, all other titles that Mr Collins provides and which I've read. "When they're this good, short novels come close to perfection in a manner for which longer novels are simply not equipped."

I thought I might try to identify some very short crime(ish) novels I have read and that made sufficient impact on me (in one way or another) that I remember them well, sometimes years later: 

TR Therese Raquin by Emile Zola

The Thin Man by Dashiell Hammett

The Time Machine by H G Wells

The Comfort of Strangers by Ian McEwan

A Moveable Feast by Ernest Hemingway

BridgeSLR Cop Hater by Ed McBain

Thumbprint by Friedrich Glauser

The Bridge of San Luis Rey by Thornton Wilder

Slaughterhouse Five by Kurt Vonnegut

CR Cannery Row by John Steinbeck

The Turn of the Screw by Henry James

Hotel du Lac by Anita Brookner.

Any other suggestions of 100-ish page novels that made an impression (does not have to be a positive one)?
