The Wonder of Whiffling is the new book by Adam Jacot de Boinod. I enjoyed his previous book, The Meaning of Tingo, when it arrived in my christmas stocking. I guessed, and have just had it confirmed, that he must be related to the man with the pet owl who used to live downstairs from us. Not the most Holmesian of deductions, given how many 'Jacot de Boinod's there are around. I love the book design and illustrations as well as the bits about words.
