I have adopted the standard of only listing the names of comics creators here if they appear on the cover of the issue. This comic has no creators listed on the cover, so I am not troubling you with their names.
This is a piece of Sherlock Holmes pastiche written and drawn by modern day creators. In episode one, Holmes was in a locked room with some fellow who was then shot dead – and when the rozzers burst in, they found an agitated Holmes standing over the dead man, holding a revolver that had just been fired. So, has Holmes turned into a murderer, or is he somehow being framed for a crime he didn't commit? Whichever it was, last issue saw him bust out of chokey, and in this one he bumbles around London disguised as a decrepit old man while Doctor Watson tries to work out what's going on. Meanwhile someone else tries to kill some continental royal fellow who is over on a visit. But apart from all that, arguably not that much happens here – it's very atmospheric, but maybe this could do with moving a bit quicker.
