What should a detective do in a dreary, rainy day? Maybe fate will send him some complicated and interesting case for unraveling? However, if there is no such thing, you can just come up with it - and it will be so confusing as far as imagination is enough.

And the truth: it is only to connect the imagination, how the plot of the murder unfolds before our eyes, and one riddle after another comes before our eyes to be solved by Sherlock Holmes. After all, no one else knows how to dexterously determine the growth of a criminal, what kind of cigars he smokes and what his profession is.
