Doctor Who Time Machination

Tony Lee (w) o Paul Grist (a & c)
London, 1889 and a time-stranded Doctor needs the help of an old friend to fix the TARDIS... but is beset by pursuers sent by Queen Victoria herself! How is this connected to a previous tale of the Sixth Doctor-and a Fourth Doctor adventure that hasn't happened yet? And what will happen if the Doctor is captured by the Torchwood Institute? Tony Lee and Paul Grist tell this special standalone tale!
