I am very proud of the logic in this one. Technically the rule about 1/5/9 is not required for a unique solution but it makes the logic flow very smoothly in my opinion. Also, the surprise ending surprised me too! It was a happy accident of the geometry. Anyway, hope you enjoy solving this as much as I enjoyed setting it!
Solution code: Row 5, left to right.

Dutch whispers feel like faintly familiar language, ”this feels right, but, is it really?”. My head hurts, thank you :)

Great puzzle! It's fun to seek out the locations of the 1/5/9's
