Visible and Invisible

"Tried for the murder of her husband six months ago," he said. "Odd case. The point is that she is the one and perfect housekeeper. I once had four servants, and everything was all mucky, as we used to say at school. Now I live in amazing comfort and propriety with one. She does everything. She is cook, valet, housemaid, butler, and won't have anyone to help her. No doubt she killed her husband, but she planned it so well that she could not be convicted. She told me quite frankly who she was when I engaged her."Of course I remembered the whole trial vividly now. Her husband, a morose, quarrelsome fellow, tipsy as often as sober, had, according to the defence cut his own throat while shaving; according to the prosecution, she had done that for him. There was the usual discrepancy of evidence as to whether the wound could have been self-inflicted, and the prosecution tried to prove that the face had been lathered after his throat had been cut. So singular an exhibition of forethought and nerve had hurt rather than helped their case, and after prolonged deliberation on the part of the jury, she had been acquitted. Yet not less singular was Horton's selection of a probable murderess, however efficient, as housekeeper. He anticipated this reflection."Apart from the wonderful comfort of having a perfectly appointed and absolutely silent house," he said, "I regard Mrs. Gabriel as a sort of insurance against my being murdered. If you had been tried for your life, you would take very especial care not to find yourself in suspicious proximity to a murdered body again: no more deaths in your house, if you could help it. Come through to my laboratory, and look at my little instance of life after death."Certainly it was amazing to see that little piece of tissue still pulsating with what must be called life; it contracted and expanded faintly indeed but perceptibly, though for nine hours now it had been severed from the rest of the organisation. All by itself it went on living, and if the heart could go on living with nothing, you would say, to feed and stimulate its energy, there must also, so reasoned Horton, reside in all the other vital organs of the body other independent focuses of life.
