A James Bond type of thriller that stars Roger Moore in his pre-Bond days (four years before he appeared in the 1973 Live and Let Die) and in his first role in a British feature (he played The Saint in a television series). The writers are transplants from the same tv series, Leigh Vance and John Kruse, which might explain why it looks like a castoff television script. The thriller, under the plodding direction of Alvin Rakoff, never jells because the mystery story remains undeveloped and muddled, the characters are one-dimensional, the acting is from hunger and the plot line the film hinges on is so preposterous it can’t be believed (…) It’s set in Swinging London and seems like a practice run for Moore’s future Bond career. Unfortunately not even the action scenes work that well in this dull thriller, as the film is as dumb and tedious as its plot contrivances. — Dennis Schwartz
