From million-copy bestselling author David Walliams comes his first ever murder mystery – with thrills, spills and laughs galore.
Dilly loves murder-mystery novels. Sherlock Holmes is her favourite detective - she even named her dog Watson after his faithful companion, and trained him to sniff out clues and follow trails.
So far, Dilly and Watson haven’t cracked many cases. But now the detective duo find themselves on a luxury ocean liner bound for London. A thousand passengers. A thousand miles of ocean around them. It's the perfect place for a murder… Or two. Or more!
