Peinforte's Chess Game Papers (Including Burnt Clue)

A comprehensive handwritten packet of papers on Lady Peinforte's desk and fireplace, their edges yellowed with age and corners curled from frequent handling. The Doctor sorts through them with deliberate care while Ace watches the chessboard, their contents evoking mathematical precision mixed with occult symbolism. A cryptic card slips from the stack, its purpose unclear but its presence essential to decoding the mathematician's collaboration in the Nemesis plot. One page bears scorched edges from a previous burn attempt (later identified as the 'Burnt Clue in Peinforte's Fireplace'). Together, these papers represent interconnected evidence of the mathematician's hidden collaboration with Lady Peinforte, where physical documents (both pristine and burnt remnants) serve as integral components of Peinforte's occult chess-based plot.
