which led to Charles Street. The door at the bottom was closed, but unlocked. We flung it open and rushed out. I can distinctly remember that as we did so there came three chimes from a neighboring clock. It was quarter to ten."

"'How long ago was it?'
"'Oh, not very many minutes.'
"'Within the last five?'
"'Well, it could not be more than five.'
