Xena and Xander Holmes have just moved to London, England with their parents. There they find out they are the descendants of Sherlock Holmes. The siblings quickly get involved into the search for a missing painting, all while trying to adapt to their new life in England.

A light and fluffy mystery for the early junior set.
