to Professor Gregory Gilmore. At approximately 5:50 on the afternoon of October 19, Paul Cordell, husband of Mrs. Juanita Cordell, laboratory assistant to Professor Gilmore, passed my desk on his way into the laboratory. I made no effort to stop him, since my employer had previously instructed me to allow Mr. Cordell to go directly to the laboratory at any time without being announced.'"

Signed: Alma K. Dakin.'" There was an almost ominous crackle to the document as Lieutenant Kirk folded it and returned it to his pocket. Paul Cordell appeared utterly stunned by what he had heard and his once stiffly squared shoulders were slumped like those of an old man. "I don't have to tell you," Kirk said, "that the only window in that laboratory is both permanently sealed and heavily barred. No one but you could have murdered those two people. You say you saw them killed by some kind of a gun. Yet a qualified physician states both deaths were caused by a terrific blow from a blunt instrument. We found a lot of things around the lab you could have used to do the
