A simple deduction
(Book)

"Liz Eckardt, owner of the Olde Mansion Inn bed-and-breakfast in Indiana's Amish country, is offering something new: a Shelock Holmes weekend complete with Victorian treats she baked on her own street and a mystery to solve. With all the hard work she's put in to prepare, the affair should be a study in simple--until Liz deduces that something decidedly illogical is going on. As part of the fun, Liz has enlisted the help of an amateur magician to pickpocket the participants then give the items to Liz for safekeeping. But, when more possessions start disappearing, even though her visitors surely locked their doors, Liz can't help but wonder if her friend has embarked on a real life of crime. Is he the mastermind behind the thefts?" -- from the book jacket.
