Bouchercon, the Anthony Boucher Memorial World Mystery Convention, is an annual convention of creators and devotees of mystery and detective fiction. It is named in honour of writer, reviewer, and editor Anthony Boucher, and pronounced the way he pronounced his name, rhyming with "voucher". It is held annually in Autumn, each year being hosted in a different city by a different group of volunteers. The convention typically starts on Thursday and finishes on Sunday.
