Hickory Dickory Dock by Agatha Christie
Something strange is happening at the boarding house run by Miss Lemon’s sister, Poirot decides to find the answers.
Unsatisfying mystery with unnecessary twists, almost no Poirot, and can probably win the award for most tenuously titled Christie novel. It’s.… not good, rapidly deteriorating into an inane, tedious mess. ★★☆☆☆
