Sherlock Holmes and The Twelve Thefts of Christmas by Tim Major
Morose and uninspired as Christmas approaches, Holmes receives an unexpected invitation to a theatrical performance, thus beginning a challenge set by Irene Adler involving a series of "thefts."

The mystery was well done, with a hint of the paranormal, which of course Holmes disproves. I listened to the audio which was maybe a bad choice. Holmes always sounded angry rather than slightly disdainful, mean rather than aloof. I did enjoy seeing Mrs. Hudson, even if she wasn't her usual self this holiday season....
