He closed with the offer. When the night fixed for the séance arrived, the weather conditions were all that could be desired; the air was soft and calm, the moon brilliant, the sky almost cloudless, and promising only the finest weather for days to come. As the medium insisted upon a party of at least four, Brown persuaded a Mr. and Mrs. de Roscovi, Russians, to come, and they all set out together from Sudbury shortly after ten o'clock. Brown had made many inquiries in the neighbourhood as to the phantom figure, but he had only come across two people who would tell him anything about it. One, a farmer, assured him that he had on several occasions seen the ghost when driving, and that, on each occasion, it had kept abreast of his horse, even though the latter was careering along the road half mad with fright. But what terrified him most, he said, was that the apparition had no head. The other, a blacksmith, said he had seen the woman twice, and that each time he had seen her she had been carrying something tucked under her arm, which he had fancied was a head. But he had been too scared to look at it very closely, and he only knew for certain that where her head should have been there was nothing. Both he and the farmer said they had heard all their lives that the road was haunted, but for what reason they had never been able to discover, as within the past sixty years, at any rate, neither murder nor suicide was known to have taken place near the hollow. This is as far as Brown had got with his investigations when he set out from Sudbury on the night in question. The de Roscovis did not think, for one moment, that the ghost would appear. They said, few people apparently had seen it; its visits in all probability were only periodical; and weeks, months, or even years might elapse before it put in an appearance there again. "That may be, but then we have a medium," Brown argued. "I engaged her to invoke the ghost, provided it would not come of its own accord. You can invoke it, can't you, Madame Valenspin?" Madame Valenspin now seemed rather dubious. "I have never tried in the open before," she said, with a slight shiver, "but I will do my best. The conditions seem favourable; but I can't say definitely till we arrive at the exact spot." Brown, however, could not help observing that the farther they advanced into the country, which became more and more lonely, the more restless and uneasy Madame Valenspin grew. Once or twice she halted, as if irresolute whether to go on or not, and the moment she caught sight of the hollow she came to a dead stop. "Not down there," she said. "It's too dark. We'd better stay here."
