Writer David Michelinie (Iron Man, Amazing Spider-Man) and Bret Blevins (The New Mutants) deliver the first trade paperback collection of their six-part comic cult favorite, in which a suicidal alien and a plucky prostitute form a detective agency that accepts cases rejected by Scotland Yard. A Victorian setting evokes the Sherlock Holmes mysteries, spiced up with supernatural sleuthing in the manner of Doctor Who and The X-Files, with a touch of steampunk style. This collection includes a new foreword and bonus pin-up by Brandon Graham.
