I need not weary you by further narrating what occurred at this official examination.Suffice it to say that, with one or two minor exceptions, Osborne and Allen followed the precise course of reasoning prophesied by Maitland, and, as for , he courteously, but firmly, held his peace.The two officers did not, however, lean as strongly to the theory that death resulted from natural causes as Maitland had anticipated, and, I think, this surprised him.He had already told them that he expected to be able to show death to have resulted from poison hypodermically applied, and, as I overheard a remark made by Osborne to Allen, I readily understood their speedy abandonment of their natural-death theory.They were engaged in verifying Maitland's measurement of the east side of the room when Osborne said softly to his companion: "He has figured in several of my cases as a chemical expert, and when he expresses an opinion on a matter it's about the same as proved.He's not the kind that jumps in the dark.He's a lawyer as well as chemist and knows what's evidence, so I reckon we'd better see if we can make anything out of the suicide and murder theories."Maitland had asked them to send to the station for a woman to search Gwen and she had just arrived.We all requested that a most thorough examination should now be made to assure the officers that no one of us possessed the missing weapon.This done, the officers and departed for the night, assuring Gwen that there was nothing further to be done till morning, and Osborne, doubtless with a view to consoling her, said: "It may be a relief to you, miss, to know that there is scarcely a doubt that your father took his own life." This had an effect upon Gwen very different from that which had been intended.Her face contracted, and it was plain to see she was beginning to think everyone was determined toforce a falsehood upon her.Herne and Browne also prepared to take their leave.A glance from Maitland told me he wished me to remain with him a moment after the others had departed, and I accordingly did so.
When we were alone with Gwen he said to her: "I think I understand your feeling with regard to Mr.Osborne's remark, as well as your conviction that it does not represent the truth.I foresaw they would come to this conclusion, and know very well the pains they will take to prove their hypothesis." "Can nothing be done?" she asked beseechingly."It is that of which I wish to speak," he replied."If you have sufficient confidence in me to place the case in my hands, I will do everything in my power to establish the truth, - on one condition," and he glanced at her face, now pale and rigid from her long-continued effort of self-control."And that condition is?" she said quickly."That you follow my directions and permit me to order your movements in all things, so long as the case remains in my hands; if at any time I seek to abuse your faith, you are as free to discharge me as if I were a paid detective." Gwen looked searchingly at him; then, extending her hand to him, she said impulsively: "You are very kind; I accept the condition.What shall I do?"I tried to catch Maitland's eye to tell him what he should counsel her, but a man with his ability to observe conditions and grasp situations can very well do without prompting."First," he said, "you must return home with the Doctor and spend the rest of the night with his sister; I shall stay here until morning; and second, I desire that you use your utmost endeavour to keep the incidents of this evening out of your mind.You cannot, of course, forget your loss, unless you sleep," - and he gave me a look which said: "I depend on you to see to that," - "but you must not continually re-enact the scene in imagination, In the morning the Doctor will come here to bring me my camera, microscope, and a few things I shall require " - and he passed me a list he had written."If you have slept well you can be of considerable service, and may accompany him - if not, you must remain quietly at his house." With this he turned to me, and said: "She is making a condenser of herself, Doctor, and will soon break through the insulation.Sparks will be dangerous - you must secure the brush effect." He spoke quickly, and used electrical terms, that she mightnot understand him, but either he failed of his purpose, or the observation she immediately made was a strange coincidence.I believe she understood, for, while young women educated by their mothers are usually ignorant upon all the more masculine subjects, those who have long been their father's companions are ever prone to startle one with the most unexpected flashes of intelligence."I am in rather a high state of tension now," she said, turning calmly to Maitland; "but when alone the expression which has been denied me here will afford relief." Maitland glanced at her quickly, and then at me, and I knew he was wondering if she had understood.Then he said: "It is getting late.I shall expect you to sleep well and to come in the morning.Please say to the servants as you go that I shall stay here all night, and that no one must enter without permission.Good-night." She held out her hand to him, but made no reply; then she fervently kissed her father's lips, and together we left the chamber of death.
