De una película del 71, originalmente obra de teatro montada en Broadway y escrita por Jules Feiffer:
"Sooner or later there's a pattern. Sooner or later everything falls into place. I believe that. If I didn't believe that I wouldn't wake up tomorrow morning and see the sunrise. Every crime has its own pattern of logic. Everything has an order. If we cannot find that order, it's because it doesn't exist... but because we have incorrectly examined some vital piece of evidence. Let us examine the evidence. Number one: In the past six months, there have been 345 homicides commited in this city. The victims have ranged variously in age, sex, social status and color.
Number two: In none of these homicides have we been able to find the motive. Number three: Consequently, all 345 homicides remain unsolved.
So much for the evidence. A subtle pattern begins to emerge. What is this pattern? What is it that these 345 homicides have in common? They have in common three things:
A: they have nothing in common;
B: they have no motive;
and C: they remain unsolved."
