For some days I thought I had found an answer to
the problem, but then a telegram arrived from
Holmes, who was now in Switzerland. It said, 'M is no
more. Returning Saturday. Holmes.'
Suddenly I realized that I
was afraid of seeing him
again, and my worry
returned, stronger than
ever. Was he the killer or
not? I had to know the
truth - and quickly. To
help me think clearly, I
wrote down what I knew.
