BIGGLES' SECRET ASSIGNMENTS
W.E.Johns
Crows Nest - NZ$39.99

Biggles becomes involved in four undercover operations in this third omnibus edition of his classic adventure stories.

I read all of the Biggles books when I was a kid growing up in Gisborne way back in the 1950's, along with the Just William series, Enid Blyton's Famous Five & Secret Seven series and of course the Swallows and Amazons series by Arthur Ransome. All borrowed from the library of course.
Amazingly these various series of books are still in print. Biggles has had a bit of a bad rap in recent yewars but I'm glad to see them being reissued in these handsome omnibus editions.
W.E.Johns died in 1968 but one imagines his estate in is good financial form.
