Dr Smallbrook

In the novel They Came to Baghdad, Dr Smallbrook is an operative of of "The New Order" secret organisation who appears towards the end of the story.

The organisation has succeeded in kidnapping Grete Harden (whom they think is Anna Scheele). Victoria Jones (who has offered to help the "New Order") is sent it to impersonate her and she arrives and is checked into the Babylonian Palace hotel in Baghdad. From there, Dr Smallbrook calls the U.S. embassy. He says he is acting for Anna Scheele and has some documents which she wants them to pick up. Anna cannot come to the phone herself as she is ill in bed with laryngitis.

Later, Dr Smallbrook is arrested when Victoria is rescued by British intelligence agents. It is not clear if Dr Smallbrook is a real doctor. But considering that the organisation would expect that people he is dealing with such as the U.S. embassy would check on his bona fides, they would be careful to use a real doctor or at least someone whose cover can withstand scrutiny.
