The Big Six first U.S. edition 1941
The original price was $2.00
Dedicated to "Margaret and Charles Renold". Renold was a fishing friend who was persuaded by Ransome to try sailing. The Renolds did not take to the dinghy "Coch-y-bonddhu", finally giving her back to Ransome. She appears in "The Picts and the Martyrs" as "Scarab". The Renolds' pug-dog appears as William in this book and in Coot Club. It is possible that Margaret Renold gave Ransome the idea of writing this detective novel.
