Maskerade (Discworld )
There are strange goings-on at the Opera House in Ankh-Morpork.  A  ghost in a white mask is murdering, well, quite a lot of people, and two witches (it really isn't wise to call them "meddling, interfering old baggages"), or perhaps three, take a hand in unraveling the mystery. Fans of the popular Discworld will be happy to see some old friends again inMaskerade, the 18th novel in the series.--Blaise Selby--This text refers to an out of print or unavailable edition of this title.
