A mist came over Blanche Farrow's eyes. She turned suddenly sick and faint. She put out her hand blindly. Gifford took it, and made her sit down on a stone bench. "I'm sorry," he said feelingly, "very, very sorry to have had to tell you this dreadful thing, Blanche." "Never mind," she muttered. "Go on, Mark, if there's anything else to say--go on." As he remained silent for a moment, she asked, in a dull, tired tone: "But if this awful thing is true, how was it found out, after so many years?" "It's a peculiar story," he answered reluctantly. "The late--I might say the last--Mrs. Varick, whose name, as you of course know, was Millicent Fauncey, had first as governess, and then as companion, an elderly woman called by the extraordinary name of Pigchalke. This Julia Pigchalke seemed to have hated Varick from the first. She violently disapproved of the engagement, quarrelled with Miss Fauncey about it, and the two women never met after the marriage. But Miss Pigchalke evidently cared deeply for poor Mrs. Varick; I've seen her, and convinced myself of that." "What is she like?" asked Blanche suddenly. "Well, she's not attractive! A stout, stumpy, grey-haired woman, with a very red face." Blanche covered her eyes with her hands. "Go on," she said again, "go on, Mark, with what you were saying." "Where was I? Oh, I know now! When Mrs. Varick died, within less than a year of her marriage, Miss Pigchalke suspected foul play, and she deliberately set herself to track Lionel Varick down. She made it her business to find out everything about him, and but for her I think we may take it that he would have gone on to the end of the chapter a respectable, and in time highly respected, member of society." There was a pause. Blanche was staring before her, listening. "About five weeks ago," went on Mark Gifford quietly, "Miss Pigchalke got into touch with the head of our Criminal Investigation Department. She put before him certain--one can hardly call them facts--but certain discoveries she had made, which led to the body of the first Mrs. Varick being exhumed." Blanche Farrow uttered a stifled exclamation of surprise, and Gifford went on: "I may add that Miss Pigchalke behaved with remarkable cunning and intelligence. She found out that the doctor at Redsands--the place where her poor friend died--was a firm friend of Varick's. She thinks him an accomplice, but of course we regard that as nonsense, for we've found out all about the man, and he is coming to see our toxological expert to-morrow." (Then that was Dr. Panton's urgent appointment in town.)
