Raphael, Frederic. "Stories from the Source of Heartlessness."

The Times Literary Supplement, No. 4618, October 4, 1991, p. 28.

An assessment of Dahl's career, noting that he was a mass-market writer but comparing him to some of the finest prose stylists of the twentieth century. Raphael theorizes that Dahl's war experiences as a fighter pilot, which he wrote about in the stories collected in Over to You, are responsible for the bitterness and cruelty of much of his later fiction.
