For two or three days he went about, asking for information concerning the coining, and reading up details in old newspapers about the exploits of the Saul family. Also, he went occasionally to the salon of Senora Gredos. There he constantly met Hale and Clancy. Also Basil came at times. That young man now adopted a somewhat insolent demeanor towards the pair, which showed that he was now out of their clutches and no longer had cause to fear them. Jennings felt sure that Basil could explain much, and he half determined to get a warrant out for his arrest in the hope that fear might make him confess. But, unfortunately, he had not sufficient information to procure such a thing, and was obliged to content himself with keeping a watch on young Saxon. But the man sent to spy reported nothing suspicious about Basil's doings. In this perplexity of mind Jennings thought he would see Cuthbert and relate what he had discovered. Also he hoped that Mallow might interview Juliet and learn the truth from her. But an inquiry at Mallow's rooms showed that he had gone out of town for a few days with his uncle, and would not be back for another two. Pending this return, Jennings sorted his evidence. Then he was surprised to receive a letter from Mrs. Herne, stating that she had returned to her place at Hampstead, and asking him to call. "I understand from Mr. Clancy," wrote Mrs. Herne, "that you wish to see me in connection with the death of my poor friend. I shall be at home to-morrow at four." Then followed the signature, and Jennings put away the note with a rather disappointed feeling. If he was right in suspecting Mrs. Herne, she certainly felt little fear, else she would have declined to see him. After all, his supposition that the two women and the four men formed a gang of coiners, who worked in the unfinished house, might turn out to be wrong. "But I'll see Mrs. Herne and have a long talk with her," said Jennings to himself. "And then I'll show the knife to Cuthbert Mallow. Also I may examine the unfinished house. If coiners have been there, or are there, I'll soon find out. Mallow hunting for ghosts, probably, made only a cursory examination. And I'll take Drudge to Hampstead with me." Drudge was a detective who adored Jennings and thought him the very greatest man in England. He was usually employed in watching those whom his superior suspected, and Jennings could always rely on his orders being honestly executed. In this instance Drudge was to wait some distance from the house of Mrs. Herne until Jennings came out again. Then on the conversation which had taken place would depend further orders. The man was silent and lean, with a pair of sad eyes. He followed Jennings like a dog and never spoke unless he was required to answer a question.
