  Literary significance and reception
  The verdict by Maurice Willson Disher in The Times Literary Supplement of 14 June 1941 was positive: "To maintain a place at the head of detective-writers would be difficult enough without the ever increasing rivalry. Even Miss Christie cannot stay there unchallenged though she has a following which will swear her books are best without reading the others. Unbiased opinion may have given the verdict against her last season when new arrivals set a very hot pace; but Evil Under the Sun will take a lot of beating now." After summarising the plot, Disher concluded: "Miss Christie casts the shadow of guilt upon first one and then another with such casual ease that it is difficult for the reader not to be led by the nose. Everybody is well aware that any character most strongly indicated is not a likely criminal; yet this guiding principle is forgotten when Miss Christie persuades you that you are more discerning than you really are. Then she springs her secret like a land-mine."
