R D Rosen has had a successful career as a mystery novelist.  His series – I’m a big fan – centers on a retired major league baseball player, Harvey Blissberg.  His new book, Tough Luck,  is non-fiction, the biography of NFL quarterback Sid Luckman centers on a solved, if under-reported murder, committed by the athlete’s father.  Part of Rosen’s research involved telling Sid’s son what his Grandfather had done and how his father – and collaborative sportswriters -- had kept it a secret.
