This is an unexceptional--for the most part a generic failing--story but it does have a mystery, in fact two, and except for the dark night when ""Mommy"" ""snuggles up"" with Abby, eleven, it's an average homestyled family setting. The Hubbards inherit an old New England coastal house, with a secret closet, a smuggler's tunnel, and a ghost that walks while shutters bang. Then there's the fact that an antique desk disappears. In the present, the house is being used as a temporary depot for stolen furniture; in the past it had belonged to a privateer and a skeleton and pieces of eight are dislodged. Ninth in a series which is for omnivores of this age group--aren't they all.
