The first thing i want to say is that this book was first published in 1921, not 1938. My copy, a hardback published by Ward, Lock & Co., was probably published in 1923 because the owner wrote their own name inside, and a date of 27/9/23.
I would definitely recommend this book as a light-hearted read, with some humorous conversations and antics. There's also a Sealyham terrier called Nobby. Look up old photos of the breed if you want to see what he looked like..
