Maybe that's a good thing. You might have more time now to study puzzle-making. :-)

sorry to hear about that. hope you find it.

Found to require some guessing by jan.

So the top parts of this are easy to solve. It's just the red that is tricky.

If you do all the line solving, you'll 8 columns of the red 19 placed in the center, and a three cells of the red 5 in column 30.

The trick is to consider the red 2 in column 29. There are just two places it can be, and the bottom position gets you into immediate trouble. It forces the red five into the top position, when means the 19 must extend all the way to column 30, which makes a mess of column 29. So the red 2 must be on top, and the 19 is placed.

That just leaves a diagonal line on the left. It's obvious enough what it probably is, but I've never yet found any way to prove that the obvious solution to such diagonals is the only solution. So I guess this is a guessing required puzzle, though not much guessing.

I'm always misplacing books. I did leave one in the refrigerator once, back in the days when I was single and there was lots of empty space in my fridge. You could look there.

I had no problem solving this puzzle. Just following the grids helped to find all the reds with no difficulties. The only thing that I can say about this puzzle is that it is boring.
