The Monthly Film Bulletin wrote: "This Anglo-American thriller contains plenty of vigorous action, but the story has many weaknesses, and the characterisation is thinly conventional. Of the international cast, Keefe Brasselle makes an effective Brett and Karel Stepanek is suavely sinister as the German conspirator Langford. Above average camerawork shows off the Middle East backgrounds to good effect."
Kine Weekly wrote: "Colourful action melodrama, staged in the Middle East and London. ... Vigorously acted by a talented international cast, ambitiously mounted and generously flavoured with sex, it hands out plenty of thrills. Just the stuff to give the ninepennies. ... Its backgrounds are suitably varied, and the climax, although grim, is showmanlike. In all, hearty, bustling hokum."
Picture Show wrote: "Fast moving with plenty of thrills and an attractive leading lady in the form of Kay Callard."
TV Guide called it an "okay suspense story with a dull romantic subplot." In
British Sound Films: The Studio Years 1928–1959 David Quinlan rated the film as "average", writing: "Interesting suspense drama slowed down by love interest." ==References==
