The Crimes of Thomas Brewster (audio story)

The Crimes of Thomas Brewster is a 2011 Big Finish Productions audio play and is the first in the 2011 Sixth Doctor audio trilogy.

It is notable for featuring the third appearance of Anna Hope's DI Patricia Menzies character, for turning Fifth Doctor companion Thomas Brewster into an assistant of the sixth, and for retconning Evelyn Smythe's personal timeline to show that there was a period of time where she shared the TARDIS with another companion.

Publisher's summary
''Sent down south to assist the Metropolitan Police in their efforts to investigate the gangland kingpin known only as 'the Doctor', Detective-Inspector Patricia Menzies finds herself up to her neck in laser-armed robot mosquitoes, gun-running criminal overlords, vanishing Tube trains... and not one, but two Doctors.''

Meanwhile the real Doctor, and his academic assistant Professor Evelyn Smythe, have become ensnared in the machinations of an old acquaintance – time-travelling Victorian guttersnipe Thomas Brewster. But what's Brewster's connection to the rapacious robot Terravores? And can anyone contain the gathering swarm?

Continuity

 * This is the Doctor's first meeting with D.I. Menzies in his personal timeline. However, it is their third meeting in her personal timeline, following BFA: The Condemned and BFA: The Raincloud Man. Menzies elects not to inform the Doctor but he correctly assumes that this is the case. He promises to return the favour when they meet for the first time from her perspective.
 * Menzies tells Evelyn of the time that Charley Pollard claimed to have met the Doctor out of order. (BFA: The Raincloud Man)
 * In BFA: The Raincloud Man, the Doctor politely refuses D.I. Menzies' request to travel with him, citing the growing mystery surrounding Charley Pollard's true identity, though he states that one day he may return and take her up on the offer. As his encounter with her in that instance takes place earlier in his personal timeline than that the events of this story, he would have been aware that Menzies did not or, from his perspective, would not become his companion in 2008. Consequently, granting her request on that occasion would have altered history and damaged the Web of Time. It is possible that the Doctor's grounds for refusal, namely the mystery surrounding Charley, may have simply been an excuse to avoid revealing to Menzies that he had already met her future self.
 * Captain Ruth Matheson would later tell Warrant Officer Charlie Sato about the 2010 Terravore incursion in the London Underground. (CC: Tales from the Vault)
 * The Doctor and Evelyn were previously imprisoned the Tower of London in 1554 (BFA: The Marian Conspiracy) as well as visiting it in an alternative 2003 (BFA: Jubilee).
