Rules:

Normal Sudoku rules apply.

RENBAN- Numbers on the 3 purple lines (Professor Plum) are each a set of non-repeating, consecutive numbers, in any order.

CONSECUTIVE PAIRS- Two-cell vertical lines of four different colors (library books) only appear on shelves between rows 1 and 2, 3 and 4, 5 and 6, or 7 and 8 respectively. A book indicates the pair is consecutive. No book means that the vertical pair is NOT consecutive. If Professor Plum is in front of a possible book (3 places), there is no negative constraint. Horizontal consecutiveness is also not negatively constrained/ considered in the puzzle.

BLACK KROPKI DOTS- Numbers with a black dot between them are in a ratio of 2:1. ALL possible black dots between orthogonal neighbors (vertical AND horizontal), throughout the ENTIRE PUZZLE, are shown.

Professor Plum says he is looking for a candlestick (no effect on the puzzle).
