four o'clock in the afternoon
But I want you to consider the tremendous gap between the fact of the knife known to belong to me , and the accusation that with this knife I murdered Mr. Edward Wilson . Now , will you please think carefully . It has been urged that I did this deed in cold blood . It was between three and four o'clock in the afternoon when I had a quarrel with Wilson and he struck me down . My servants have given testimony to the fact that I came home , talked with my mother , went into my study , stayed there for several hours . Then it is urged that I went out , carrying this knife with me ; and , mark you , they did not see the knife in the house , no one saw me take it away from the office ; but it is urged that I went out , after several hours ' cool and calculated thought , at midnight ; that I caught the murdered man unawares , drove the knife into his body , and then ran away and left it there . Now , think of this , gentlemen , and remember that my life or death depends upon the reasonableness of it , depends upon this link in the chain of circumstantial evidence .
