Pilgrim (organisation)
From Tardis Wiki, the free Doctor Who reference
Pilgrim was a Cardiff-based discussion group on metaphysical and philosophical topics, to which Suzie Costello, a Torchwood 3 operative who led a double knife as a serial murderer belonged. Torchwood 3 suspected the Pilgrims of involvement in the murders of Alex Arwyn, Mark Briscoe and Sarah Briscoe. Other than Costello, Pilgrim members included Lucy McKenzie and a man known as Max (TW: They Keep Killing Suzie).
