This is a well-told story which made me keep turning page after page. There are many suspenseful scenes which keep the reader wondering if all will go well. I found the manner in which Aunt Eleanor came to suspect Captain Derek Wainwright's (aka Jonathan Derek Wentworth) true identity quite humorous. The duke's investigation of the smuggling ring does not overrun the story. There are also a couple of unexpected and surprising twists near the end.
