Lofting's wife's sister, dancer Olga Fricker, completed the book and was published posthumously in 1950. Everything except the first and last chapter are by Lofting.

Much of the book is repeated from the 1926 novel, Doctor Dolittle's Caravan. It tells the story of the Doctor's friend Pippinella the Green Canary, in slightly greater depth.

This copy has a fold on the front cover and shows signs of age and wear and tear, but is complete and perfectly readable.
