I listened to a solid 4 hours of this audiobook while cleaning my flat and I had to pause my activies as soon as I stumbled upon a scene, where the main character is eating with a guy, who shreds his food into small pieces with his fingers.
Well, that sounded familiar to me. It took me a solid 5 minutes until i remembered that one of Agatha Christie´s characters did that. Yes, number 4 is back. Dun, Dun, Duuuuunnnnn.
One of my main problems with this book is that Horowitz constantly references Agatha Christie. And I´m not even sure to which extent he does it, because so far I have only read about 10 of Christie´s work. But it´s already enough that I can recognize it for what it is and I´m massivly annoyed by it.
