A Matter of Death and Life

Marital troubles? Sick of life? Suicide the answer? Why not get yourself a contract killer?
Nothing easier, provided you communicate only by phone and box number. You give him your photograph, specify when and where to find you, then sit back and prepare to die.
Murdered, you will be of greater interest than ever you were in life. More to him than met the eye will be the judgement. A mysterious killing lives long in the popular memory. Our hero meticulously plans his own demise, except for one detail: what if he suddenly decides he wants to live?
