Benjamin Stevenson's murder mystery is structured like a grim Advent calendar

Benjamin Stevenson's murder mystery is structured like a grim Advent calendar AYESHA RASCOE, HOST: Christmas is about two weeks away, and I can't wait to open presents with my kids then relax, maybe snuggle up with some nice wine and read my way to a holiday escape. The book is by Australian comedian Benjamin Stevenson, and it's called "Everyone This Christmas Has A Secret." STEVENSON: Well, I think that's what's so great about Christmas mysteries, is it's supposed to be kind of joyous and happy, and then something really dark happens, like a murder. STEVENSON: It was really fun to do because it's something that I've put off doing because, as I said before, one of the rules of fair-play mysteries is that you're not allowed to have identical twins in it.
