Gr 4-7-- Shortly after 12-year-old Xena and her younger brother Xander move with their parents to London from Florida, they discover that they are the direct descendents of Sherlock Holmes and they receive his notebook of unsolved cases in this first title (Holt, 2008) in the series by Tracy Barrett. The youngsters are determined to try to solve a case, and settle on one involving a long-missing portrait by the artist Nigel Batheson. There is an exhibit of his work scheduled to open at a local museum, so the children feel a connection to the case. Following one clue after another, as well as some miscues, the siblings use their particular talents of exceptional memory and observation to find a solution. Likeable characters, an intriguing premise, and references to original Sherlock Holmes stories combine for a fun telling. David Pittu does a laudable job reading the tale and has an excellent sense of timing. He gives each character a unique voice and brings the various personalities to life. An enjoyable beginning to a new series.--Deanna Romriell, Salt Lake City Public Library, UT[Page 74]. Copyright 2008 Reed Business Information.
