A proto-version of the SOE was formed in 1938 after Germany annexed Austria. Originally, the organization was three independent war departments merged into one. Those Departments were: The Electra House, a Propaganda Organization created and headed by the Foreign Office, referred to as (SO1), MI6's Section (D) Destruction, (SO2) and MI6(R) Research (SO3).
Eventually, SO3 and SO2 merged into one entity and SO1 was separated and became its own War Department, Political Warfare Executive. This changing of departments and duties, led to near constant arguments between the formally independent units on the the subjects of duties and responsibilities, the sharing of information and the chain of command, which in turn, led to a revolving door of new Leadership.
The Formal and Official Founding of the SOE came on July 22, 1940, when Winston Churchill and Lord Hankey persuaded Section D and MI6(R) to coordinate their operations and "Set Europe Ablaze"

S.O.E. F Section referred to the agents and spies trained for and deployed to France. These agents were trained in sabotage, and wireless radio work. Most training focused on agents finding (or in the case of Virginia Hall) setting up an intelligence network once on the ground.

This aspect of the job would be the most dangerous, since agents were often exposed because they trusted the wrong person or because of another agent's carelessness. For example Violet Szabo was captured because the other operative she was working with insisted on using a car for a mission, even though a bicycle would have be less obvious and was the safer choice.
The French Section of the S.O.E was moved to 64 Baker Street on October 31, 1940. And like how the C.I.A. Headquarters is called Langley, after the Virginia neighborhood, which it resides, and how the street name for the London Metropolitan Police Department became a euphemism for the department itself -Scotland Yard. Likewise, the S.O.E became referred to simply as Baker Street.

The term: The Baker Street Irregulars was invented by Sir Arthur Conan Doyle to describe the network of street boys Sherlock Holmes employed as a spy network for intelligence work.
Since the Head Quarters for the S.O.E. was at 64 Baker Street. Many agents and operatives inside and outside the department started referring to S.O.E. Agents as The Baker Street Irregulars.
The Baker Street Irregulars appear in two Sherlock Holmes novels and one short story:
