'They'll never suspect us in the world, Mike,' she said. 'It's the lieutenant's knife that did it, and, as he was going to fight him anyhow, he'll get the credit of it all.' Then we drove up the levee, put Waring in Anatole's boat, sculls and all, and shoved him off. 'I'll muzzle Jim,' she said. 'I'll make him believe 'twas he that did it when he was drunk.' She took most of the money, and the watch and ring. She said she could hide them until they'd be needed. Then I drove Philippes up to town until I began to get so sick and faint I could do no more. I turned the cab loose and got away to a house where I knew they'd take care of me, and from there, when my money was gone, they sent me to the hospital, thinking I was dying. I swear to God I never meant to more than get square with the lieutenant. I never struck Lascelles at all; 'twas she who drove the knife into his heart." Then, exhausted, he was led into an adjoining room, and Mrs. Doyle was marched in, the picture of injured Irish innocence. For ten minutes, with wonderful effrontery and nerve, she denied all personal participation in the crime, and faced her inquisitors with brazen calm. Then the chief quietly turned and signalled. An officer led forward from one side the wreck of a cabman, supported by the priest; a door opened on the other, and, escorted by another policeman, Mrs. Dawson re-entered, holding in her hands outstretched a gingham apron on which were two deep stains the shape and size of a long, straight-bladed, two-edged knife. It was the apron that Bridget Doyle had worn that fatal night. One quick, furtive look at that, one glance at her trembling, shrinking, cowering kinsman, and, with an Irish howl of despair, a loud wail of "Mike, Mike, you've sworn your sister's life away!" she threw herself upon the floor, tearing madly at her hair. And so ended the mystery of Beau Rivage. There was silence a moment in Cram's pretty parlor when the captain had finished his story. Waring was the first to speak: "There is one point I wish they'd clear up." "What's that?" said Cram. "Who's got Merton's watch?" "Oh, by Jove! I quite forgot. It's all right, Waring. Anatole's place was 'pulled' last night, and he had her valuables all done up in a box. 'To pay for his boat,' he said." * * * * *
