Query: Bill Adler Jr - spoiler extrordinaire

An occasionally interesting collection of 22 short stories, written over a wider timescale than is normally seen in anthologies, albeit the inclusion of Edgar Allan Poe's 1850 contribution is one of several which invalidate the word 'machine' in the title! This claims the collection to be 'the best ever written', but apparently not from any poll, simply the opinion of editor Adler. It would have been nice to see genuine claimants such as Robert A Heinlein's 'All You Zombies' included, but apparently the editor considered his own rather insipid tale to have more merit. This self-indulgence comes to a head with the inclusion of an editorial spoiler at the beginning of each and every story. Unless you make a point of avoiding reading these, the whole effect of a professionally unfolded plot is destroyed. Left to their own devices, without the interference of intrusive editing, this collection of varying quality stories would deserve a 3.
