John Blake seems to have committed the perfect crime. He has killed Thomas Evers, just as he told Blackie that he would. Blake also has a perfect alibi and seems to be making a fool out of Blackie! John Blake, a student of crime has come urgently to see Blackie. He wants to know why a murderer is always caught? Blackie replies “that’s easy because they always make a mistake.” John Blake would like to differ and informs Blackie that he is going to murder a man named Thomas Evers, he won’t tell him where or when but defies Blackie to prove it.
