Unfortunately for the young 'Musics With Rocks In' Star, supernatural forces have conspired that he should live fast.

She only met her grandfather once or twice as a young child, and afterwards was raised by her parents to take a very cold and rational view of things, which is not much of a survival trait on the Disc. There are two interconnected plots: in the first, the deaths of Mort and Ysabell in a car(t) crash cause another case of Death Takes a Holiday after a Heroic BSoD, leading to his 'granddaughter' (Mort and Ysabell's daughter) Susan taking over The Duty, and incidentally becoming one of Disc fandom's favourite characters.

Susan just had to ask her grandfather to take his vest off.
