On 25th March 1918 Vlad the flea and his friend, Crisp VC the carrier pigeon, are on a mission to deliver a secret message from behind enemy lines.

They must dodge the dog-fights, survive the trenches and seek help from the staff of the hospital tent as they race to reach Britain safely.

In this adventure Vlad encounters Skipper Thomas Crisp, Second Lieutenant Walter Tull, Dr Phoebe Chapple and the Red Baron.

The Vlad flea books are a series of historically accurate stories narrated by Vlad himself. In them he weaves a tale about the events he sees and in the process tells his young listeners about moments in history. These books include a fact file giving further details and clarifying what really happened all those years ago.
