Whilst I was still investigating the room there came the sound of wheels on the gravel outside the house.  There was a ring at the hall door, and a few minutes later, after a preliminary tap at the door and an answering “Come in!” Doctor Winchester entered, followed by a young woman in the dark dress of a nurse.

“I have been fortunate!” he said as he came in.  “I found her at once and free.  Miss Trelawny, this is Nurse Kennedy!”

Chapter III The Watchers

I was struck by the way the two young women looked at each other.  I suppose I have been so much in the habit of weighing up in my own mind the personality of witnesses and of forming judgment by their unconscious action and mode of bearing themselves, that the habit extends to my life outside as well as within the court-house.  At this moment of my life anything that interested Miss Trelawny interested me; and as she had been struck by the newcomer I instinctively weighed her up also.  By comparison of the two I seemed somehow to gain a new knowledge of Miss Trelawny.  Certainly, the two women made a good contrast.  Miss Trelawny was of fine figure; dark, straight-featured.  She had marvellous eyes; great, wide-open, and as black and soft as velvet, with a mysterious depth.  To look in them was like gazing at a black mirror such as Doctor Dee used in his wizard rites.  I heard an old gentleman at the picnic, a great oriental traveller, describe the effect of her eyes “as looking at night at the great distant lamps of a mosque through the open door.”  The eyebrows were typical.  Finely arched and rich in long curling hair, they seemed like the proper architectural environment of the deep, splendid eyes.  Her hair was black also, but was as fine as silk.  Generally black hair is a type of animal strength and seems as if some strong expression of the forces of a strong nature; but in this case there could be no such thought.  There were refinement and high breeding; and though there was no suggestion of weakness, any sense of power there was, was rather spiritual than animal.  The whole harmony of her being seemed complete.  Carriage, figure, hair, eyes; the mobile, full mouth, whose scarlet lips and white teeth seemed to light up the lower part of the face—­as the eyes did the upper; the wide sweep of the jaw from chin to ear; the long, fine fingers; the hand which seemed to move from the wrist as though it had a sentience of its own.  All these perfections went to make up a personality that dominated either by its grace, its sweetness, its beauty, or its charm.

Nurse Kennedy, on the other hand, was rather under than over a woman’s average height.  She was firm and thickset, with full limbs and broad, strong, capable hands.  Her colour was in the general effect that of an autumn leaf.  The yellow-brown hair was thick and long, and the golden-brown eyes sparkled from the freckled, sunburnt skin.  Her rosy cheeks gave a general idea of rich brown.  The red lips and white teeth did not alter the colour scheme, but only emphasized it.  She had a snub nose—­there was no possible doubt about it; but like such noses in general it showed a nature generous, untiring, and full of good-nature.  Her broad white forehead, which even the freckles had spared, was full of forceful thought and reason.
