This film caught my attention solely on the basis of the title. An rather implausible wartime yarn of how British Military Intelligence attempt to track down a kidnapped Swedish scientist who may be on the verge of a major breakthrough in nuclear technology. The story moves along at pace on the basis of hunch and coincidence, but that said moves along in an enjoyable way. Robert Newton is fine as the lead, but the real star for me at least is Guy Middleton who provides amusing quips throughout. Edited by Flora Newton one of a number of women editors working in the British Film Industry at this time.
