She broke off with a little shudder. It was a relief to Framton Nuttel when the aunt bustled into the room with a whirl of apologies for being late in making her appearance.
"I hope Vera has been amusing you" she said.
"She has been very interesting," said Framton.
"I hope you don’t mind the open window," said Mrs. Sappleton briskly. "My husband and brothers will be home directly from shooting, and they always come in this way. They’ve been out for snipe in the marshes today, so they’ll make a fine mess over my poor carpets. So like you menfolk, isn’t it"
She rattled on cheerfully about the shooting and the scarcity of birds, and the prospects for duck in the winter. To Framton it was all purely horrible. He made a desperate but only partially successful effort to turn the talk on to a less ghastly topic; he was conscious that his hostess was giving him only a fragment of her attention, and her eyes were constantly straying past him to the open window and the lawn beyond. It was certainly an unfortunate coincidence that he should have paid his visit on this tragic anniversary.
"The doctors agree in ordering me complete rest, an absence of mental excitement, and avoidance of anything in the nature of violent physical exercise," announced Framton, who laboured under the tolerably widespread delusion that total strangers and chance acquaintances are hungry for the least detail of one’s infirmities, their cause and cure. "On the matter of diet they are not so much in agreement," he continued.
"No" said Mrs. Sappleton, in a voice which only replaced a yawn at the last moment. Then she suddenly brightened into alert attention-but not to what Framton was saying.
"Here they are at last!" she cried. "Just in time for tea, and don’t they look as if they were muddy up to the eyes!"
Framton shivered slightly and turned towards the niece with a look intended to convey sympathetic comprehension. The child was staring out through the open window with a dazed horror in her eyes. In a chill shock of nameless fear Framton swung round in his seat and looked in the same direction.
In the deepening twilight three figures were walking across the lawn towards the window, they all carried guns under their arms, and one of them was additionally burdened with a white coat hung over his shoulders. A tired brown spaniel kept close at their heels. Noiselessly they neared the house, and then a hoarse young voice chanted out of the dusk: "I said, Bertie, why do you bound"
Framton grabbed wildly at his stick and hat; the hall door, the gravel drive, and the from gate were dimly noted stages in his headlong retreat. A cyclist coming along the road had to run into the hedge to avoid imminent collision.
"Here we are, my dear," said the bearer of the white mackintosh, coming in through the window, "fairly muddy, but most of it’s dry. Who was that who bolted out as we came up"
"A most extraordinary man, a Mr. Nuttel," said Mrs. Sappleton, "could only talk about his illnesses, and dashed off without a word of goodbye or apology when you arrived. One would think he had seen a ghost."
"I expect it was the spaniel," said the niece calmly. "He told me he had a horror of dogs. He was once hunted into a cemetery somewhere on the banks of the Ganges by a pack of pariah dogs, and had to spend the night in a newly dug grave with the creatures snarling and grinning and foaming just above him. Enough to make anyone lose their nerve."
