The postmistress was confounded. She could think of nothing to say in reply until the right moment for saying it had fled; and her pride forbade her acknowledging defeat by tossing her head and walking out with a grand air of injured innocence. In the end she lost her composure entirely, for while Donna's remarks had seemed designed for the “folks” whom Miss Pickett seemed to fear might “talk,” the latter knew that in reality they were directed at her. To be forced to listen to an almost motherly castigation from Donna Corblay was too great a tax upon Miss Pickett's limited powers of endurance. She flew into a rage, all the more pitiful because it was impotent, murmured something about the ingratitude of some people--“not mentionin' any names, but not exceptin' present company,” and swept out of the eating-house; not, however, until she had commenced to cry, thus acknowledging her defeat and humiliation and presenting to San Pasqual that meanest of all mean sights, a mean old maid, in a rage, weeping until her eyes and nose are red. In the afternoon Donna had a visit from a Wells Fargo & Company detective. He was a large fatherly person, who might have had girls of his own as old as Donna, and he stated his mission without embarrassment of preliminary verbal skirmishing. “From various sources around town, Miss Corblay, I gather that it is quite possible you are acquainted with the man McGraw who is suspected of the recent stage robbery at Garlock.” Donna admitted, smiling, that it was quite possible. “Have you any objection to telling me all you know about him?” “Not the slightest. It is your business to investigate this matter, and I have refrained from telling others whose business it is not. If I have your word of honor that what I tell you is for the company you represent and not for the gossips of San Pasqual, I can save you time and trouble and expense.” “Thank you. It is a rare pleasure, I assure you, Miss Corblay, for a man in my line of work to receive such a prompt, courteous and businesslike answer from a woman. You have my word that anything you tell me is in confidence.” “Did Miss Pickett send you here?” “Indirectly. She gave some information to our express messenger who in turn gave it to me. I might add that the interest of our messenger ceased when I took up this case.” “Very well” replied Donna, and proceeded to tell him with infinite detail, everything she knew concerning Bob McGraw, excepting the fact that he was her husband. In five minutes she had tightened the web of circumstantial evidence around him, and then unloosened it, and at the finish of her recital the detective had no questions to ask. He held out his hand and shook hers warmly. “I think you have solved this case for me, Miss Corblay. However, there is one matter that will be hard to overcome, and that is the identification of McGraw by the passenger, Carey.” “Who?”
