Barnaby Grimes: Curse of the Night Wolf (Unabridged)

One moment I was standing there, sword raised, knees trembling. The next, in a blur of fur and fury, the hellish creature was flying towards me, its huge front paws extended and savage claws aiming straight at my hammering heart...
Barnaby Grimes is a tick-tock lad - he'll deliver any message anywhere anytime. As fast as possible. Tick-tock - time is money! But strange things are afoot. One moonlit night, as Barnaby highstacks above the city, leaping from roof to roof, gutter to gable, pillar to pediment, a huge beast attacks. He barely escapes with his life. And now his friend Old Benjamin has disappeared.
