Woddeley's Occult Sequence

A sequence of magical locks (presumably designed by Woddeley) that is used to lock an important-looking box in Hogfather. Elements of the sequence include:

• the 5th lock is opened left-handed using a wooden pick
• the 6th lock is opened by copper and blue-green light
• the 7th lock is opened by pure white light

Mr Sideney, a junior wizard, knows this sequence, as does the assassin Teatime. Mr Brown, the best non-magical lockpicker on the Disc, does not.
