Sherlock Holmes returns to take down the last of Moriarty's criminal organization, the murderous Colonel Moran, who in turn unleashes a band of assassins led by Deadeye. Billy, Charlie, Tom, and their cat, Watson, must find a way to help stop them.

When Sherlock Holmes gives Billy, Charlie, Tom and their cat, Watson, a new case, the crew find themselves facing an extortion ring far bigger than they ever imagined. And news of Sherlock's death leaves the kids grief stricken.

"Billy, Charlie, and Tom are inseparable, and for good reason. Filled with con men and scoundrels, London's East End is not easily survived alone. Fortunately, the three friends--and their faithful feline companion--can count on the protection of Sherlock Holmes, for whom they sometimes act as spies. When Tom's girlfriend is kidnapped, the Baker Street Irregulars must put their budding sleuthing skills to use. Then, when a Russian immigrant is framed for a Jack the Ripper-inspired crime, our heroes set out to discover the truth and uncover a conspiracy that may go deeper than they ever imagined. Armed with only their quick wit and street smarts, the Baker Street Irregulars must work together to solve mysteries in the nick of time."--Provided by publisher.
