Second Bureau is a 1936 British spy romance film directed by Victor Hanbury and starring Marta Labarr, Charles Oliver and Arthur Wontner.

The continuity at the beginning, however, is distinctly confused, and for a short while there is even some difficulty in determining which of the characters is which, particularly as we know that at any given moment they may be endeavouring to disguise their identities. ...

The sequence of events, as one might expect in this type of story, is not always outstandingly logical; and at times one feels that the treatment might with advantage have been more circumstantial.

Great pains have been taken to cultivate convincing atmosphere, all the exteriors are obviously the real thing, and the good technical work is augmented by a carefully graduated and fascinating performance by Marta Labarr in the lead.
