However, he does not get much time to enjoy it, because, in the middle of the argument, his boss suffers a heart attack. And he is not the only one to die. Ponsford is haunted by death: the woman with whom he had been flirting for too long, his wife's father, one of his competitors, they all succumb. Finally, Ponsford's young son also dies.
