David Walliams: Super Sleuth

Dilly loved a good murder. Not a real murder. A made-up murder. One you would find in a murder mystery novel. Sherlock Holmes was her favourite detective, so much so that she had named her dog Watson after his faithful companion. Dilly had trained her Watson to sniff out clues and follow scent trails. Something he would happily do for a dog biscuit. Or two. So far, Dilly and Watson hadn't had much luck cracking cases, beyond lost cats, or missing biscuits that turned out to have been eaten all along. But now the detective duo found themselves on a luxury ocean liner bound for London. A thousand passengers. A thousand nautical miles of ocean around them. It was the perfect place for a murder.
