 Kell described the appointment of Thwaites as DMI in 1918 as âa very good choice too â a fortunate one for us, as he knows us all so well and appreciates our work'. Kell to Holt-Wilson, 7 Sept 1918, Holt-Wilson papers, Security Service Archives.

 According to Security Service records, Clarke left MO5, for unexplained reasons, on 30 November 1912. (Within the War Office, the cover name for Kell's Bureau was MO5(g).)

 Recent research shows that Melville was born in 1850 (Cook,
M: MI5's First Spymaster
,
p. 14
). Kell's Bureau, however, did not know his birth-date. An interwar career summary in Security Service Archives gives the date as âabout 1847'.

The earliest surviving reference to this episode appears in Kell's âProgress report for the quarter ending 30th September 1911' (filed with his diary for 1911 in TNA KV 1/10): âThe Leith case investigations are in hand, due to information received from Leith, that have led to the discovery of the name and address of a genuine German agent abroad, and the name and addresses of several of his correspondents in this country. The matter is being very carefully investigated.' Kell's progress reports never mentioned the name of the recipient of the letter (in this case Holstein). None of the surviving accounts explains how Clarke (about whom little is known) found himself in the same railway carriage as Holstein. He had originally joined a Scottish regiment and may have been visiting family and friends. Or, which is perhaps more likely, Clarke had gone to investigate reports of suspicious Germans in Leith, the port for Edinburgh.

 Though Fitzgerald, about whom very little is known, officially joined Kell's Bureau as a detective on 1 November 1912, according to the Staff Register, it is possible that, as in the case of some other early recruits, he had worked informally for the Bureau before that date.

 The British licensee of the US Roneo Company was established in 1909, making Kell one of its earliest customers. One of the founding directors and investors of Roneo was Edmund
Trevor Lloyd Williams, the founding chairman of another equally modern high-tech business, the Gramophone Company Ltd. For additional details see âGeneral Staff Policy in connection with Enemy Alien Civilians during war' in âSummary of the work and duties of Branch F of MO5', n.d., Holt-Wilson papers, Security Service Archives, and was evidently added to in the course of the war. The first round of aliens registration was evidently complete by the first anniversary of the Bureau, for on 3 November 1910 Kell noted: âThe Home Secretary approved the Aliens Return. I ordered 1500 copies to be printed by Mr C. Harrison.' Kell diary, TNA KV 1/10.
