The book consists of 10 short stories about Tam a brilliant Scottish pilot, a thriller novel fan, socialist and cigar addict. The stories of Tam the pilot are not mysteries. Tams dialogue is written phonetically and he is great fun and saves the rather silly pre-Biggles stories from being too ridiculous to be enjoyable. The characters are broad, the situations light, but the stories are exciting and fun. Tam is a real person, and all the adventures set forth have actually happened, though names and places are necessarily fictitious. These are some of the earliest examples of air pulp, which exploded in popularity a decade after this books publication, following Linderbergs famous flight, and the release of Wellmans Wings.
