"Det är dagen före julafton och i Vallebys Simhall är det dags för Stora julsimmet. Hela staden verkar vara där. Alla som vill kan försöka ta simborgarmärket. Dessutom kommer den kände simstjärnan Racke Bolander. Mitt under uppvisningen släcks ljuset. Ett brott begås och en okänd tomte smyger omkring. Tur att Lasse och Maja finns på plats."

It's Christmastime in Pleasant Valley and the town is getting ready to celebrate. But when all the lockers at the Pleasant Valley swimming pool are emptied during the Big Holiday Swim, it looks like Christmas won't be very merry. Once again, Jerry and Maya use their super sleuthing skills to help the police chief track down the mysterious thief before he ruins Christmas for the whole town. ( )

I’m beginning to run out of space to put these… But wise from the last few year’s challenges failings, I’d rather finish early than start a silly bonus category. Nothing much is new under the sky of Valleby. This time the über-clever duo stumble on a theft from the security lockers at the local swimming hall at Christmas Day, the day the Olympic diver is there to perform. This mystery features a major red herring, but unfortunately a very silly one (the local priest set out to sabotage Jesus’ competition in a Santa mask, anyone?). The biggest perk of this book for me is that a woman being in love with another woman is presented as something completely ordinary. A critical eye to normativity is becoming a regular feature in Swedish children’s books, so much so it doesn’t need to be stressed. Good. ( )
