 As this agreement is made, a large number of staff from The Institute arrive in DuPray and, following a shoot-out, several police and all but Mrs Sigsby and a doctor from The Institute are killed.Tim and Luke take the captured Mrs Sigsby back to The Institute, where her second-in-command, a man called Stackhouse, tries to ambush them.This is partially thwarted by Tim having made Mrs Sigsby drive the car to The Institute, so she is killed accidentally.
