The title novella first appeared in Sometime, Never in 1956, and "Stitch in Time" came from Magazine of F&SF in 1961 - the rest may be original. This collection has an American variant which also came out in 1961: The Infinite Moment (I don't know which came first, or if they were simultaneous.) Each contains 6 stories - but only 4 are common to both volumes. "Oh, Where, Now, is Peggy MacRafferty?" and "A Long Spoon" can only be found here.

His full name was John Wyndham Parkes Lucas Beynon Harris.

After WWII, he started writing different sorts of tales and thoughtful disaster novels like The Day of the Triffids - published as "John Wyndham."
