Lazarus' body is taken away in an ambulance. Martha's mother Francine becomes doubtful about Martha's connection with the Doctor after being informed by Harold Saxon that the Doctor is dangerous. The Doctor hears the ambulance crash and finds that the drivers have been drained of life. The Doctor, Martha and Tish chase Lazarus to the nearby Southwark Cathedral, where Lazarus sought sanctuary during the Blitz. Martha and Tish lure Lazarus to the top of the Cathedral's bell tower, and the Doctor manipulates the church's pipe organ to produce the maximum volume it can. The vibrations caused by the organ interfere with Lazarus' manipulated DNA and he falls to his death.
