The start of the spring semester brings with it a new round of Problem of the Week! This term’s theme is “Knights, Knaves, Normals, Werewolves and Other Fanciful Creatures.” That’s right! A whole term dedicated to the most endearing characters ever to populate fictional islands in logical brainteasers. The problems will get harder as we go along, but I always like to start with a few easy ones. So have a go at it, if you like.
