"When Sherlock Holmes moves out of Baker Street, a new tenant moves in-a mysterious woman named Elizabeth who has long been a fan of Holmes. When she discovers that Griffin and his uncle are also detectives, she becomes very friendly. So when Elizabeth goes missing along with a special invention, Griffin sets out to rescue her. But finding Elizabeth will take them on a race against the clock that bends time itself!"

I thought that this book, in which Holmes is retired, might be an interesting read. And all in all is was a pretty good read. Since it was the second book, I was surprised that I knew pretty much what was going on. I thought the book just a little bit scattered when the time travel came into play, but in order for Griffin to solve his mysteries he needs to travel in time.
