It is the dawn of World War I, and Sherlock Holmes has been dead for 20 years. Professor James Moriarty is a lost man, but he’s called back into the fray when MI5 blackmails him into finding Holmes’ long-lost brother, Mycroft. What at first appears to be a routine case leads to a web of intrigue that involves a psychic box and its creator, a woman from Moriarty’s past, and a new villain that threatens to be greater than Moriarty ever was.

This deluxe, hardcover edition collects issues #1-9, the first and second story arcs of the acclaimed series, THE DARK CHAMBER and THE LAZARUS TREE.
