The Crimes of Thomas Brewster was the one hundred and forty-third story in Big Finish's monthly range. It was written by Jonathan Morris and featured Colin Baker as the Sixth Doctor, Maggie Stables as Evelyn Smythe and reintroduced John Pickard as Thomas Brewster.

It was notable for featuring the third appearance of DI Patricia Menzies, for featuring the first appearance of the Doctor's future companion Flip Jackson, for turning the Fifth Doctor's former companion, Thomas Brewster into a companion of the Sixth Doctor and for retconning Evelyn's personal timeline to include a 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?
