Luke Pagan, formerly a London policeman and now a young recruit in MO5, the new intelligence service headed by Vernon Kell, is an undercover agent posing as a waiter in a Portsmouth hotel.

In his guise as a waiter, Luke encounters Erich Krieger, a wily and ruthless German saboteur-intelligence agent now passing as a haughty British major residing in Portsmouth.

With help from Vernon Kell and Admiral William (Blinker) Hall, soon to be the real-life head of Naval Intelligence, they once again thwart some of Krieger's schemes, rounding up a number of German agents in the process.
