TOAD TAKES UP TEACHING
Two years after the end of World War 1, found Toad in the Home Section of the Secret Service Bureau. For which benison he was grateful to his ex-RFC commander who had pulled the necessary strings.

Not only Toad but his invaluable comrades, Bones and the Flight had also been included. The three of them were gloomily discussing their good fortune after the manner of a dentist who has won a racehorse in a raffle.

"It's a tricky one Hall" the Colonel greeted Toad brusquely. "I need you to infiltrate a boarding school, playing the part of a teacher, in order to flush out another member of staff who is subverting the boys to gain access to their fathers top secret information.

That's all we have to go on and its our best guess based on the scientists whose work has been compromised. The adult could be anyone the boys might encounter, possibly a gardener not necessarily a teacher. So draw up a plan to present to the higher ups in a weeks time, will you?
