The two figures had been on the bridge. He had grasped hold of her. To save her, or to push her? Murder, suicide or accident? Inspector William Monk of the Thames River Police watches helplessly as the man and woman fall to their deaths.

Maddened by his obsession, he'd apparently shot himself. Mary had never accepted that. And now she was dead too. Was it chance or more sinister than that?at?
