What a beautiful puzzle! Loved the genius break in and the challenge/possible combinations in the middle of the solve.

I share the opinion of GeorgeTheToad2. The middle of the solve got quite tricky. But - again I have to say: thank you very much for creating and sharing another wonderful puzzle.

Wonderful puzzle. About 4* difficulty for me. The break in was not too difficult but I took lots of time on completing all the clues on the outside, where I had to think outside the box!
