Muggidrear, the capital city on the island of Welkin, is in danger of becoming a vampire colony! Ghostly ships are arriving from Slattland, filled with coffins, and the vampire voles are becoming a real pain in the neck. Even the Mayor's sister, Princess Sybil, has been bitten!

Montagu Syvler, the famous weasel detective, suspects that someone is deliberately sending the vampires across the seas to destroy Welkin for ever. With his trusty companions, he sets out for Slattland, determined to find - and destroy - their master. And to make matters worse, the anarchist Spindrick has a fiendish plot of his own - to put the whole city to sleep so he can wreak havoc.

Will Monty come whisker to whisker with the evil master vampire? And can he stop Spindrick before his plans get completely out of paw?
