Under the watchful gaze of the Peace Tower, while intrepid skaters traverse the Rideau Canal, four setters gather in the Learning Crossroads to let their creativity coalesce, guided by the inspiring light of this puzzle's namesake: the Château Laurier.

This is a collaboration between IkeManga, Scojo, LMDemasi and myself. We hope you enjoy!

Normal Sudoku Rules apply: Fill each cell with a digit from 1 to 9 such that digits do not repeat in any row, column or outlined 3×3 box.

Ambiguous Little Killers: Clues outside the grid give the sum of the digits along one of the diagonals emanating from that cell, to be determined by the solver.

Disjoint Detectives: The central cell of each outlined 3×3 box counts the number of times cells within that 3×3 box are used by Little Killers. If a cell is used by multiple Little Killers, that cell is counted for each Little Killer. These central cells form a complete set of the digits 1-9.
