I say, Sherlock...

Months go by, filled with your writing interminable Sherlock Holmes pastiches which pays the rent at your lodgings...

U until one night - August 31st, 1888 to be exact - A woman's body is discovered brutally murdered in Bucks Row.

Do you: Follow your informant back to the scene of the crime; place this murder on the stack of information you have about other murders in the area (currently running at three a week); or visit Bishops Gate Police station?
