Quite amusing film, with a fairly suspenseful spy plot tagging along with the comedy. Calvert makes a quite lovely femme fatale, and Huntley a nicely unctuous villain. The setpiece with Harker convincing a professor the school he is applying to is actually a reformatory for violent youths is priceless.

Note: Wally Patch is prominently credited, but nowhere to be seen. He must have been replaced by Noel Dainton, who, though wearing corporal's stripes, is carrying a swagger stick and addressed as "sergeant major" by Harker.
