The next day Lewisham was too full of engagements to communicate with Lagune, but the following morning he called and found the psychic investigator busy with the proofs of _Hesperus_. He welcomed the young man cordially nevertheless, conceiving him charged with the questions that had been promised long ago--it was evident he knew nothing of Lewisham's marriage. Lewisham stated his case with some bluntness. "He was last here on Saturday," said Lagune. "You have always been inclined to suspicion about him. Have you any grounds?" "You'd better read this," said Lewisham, repressing a grim smile, and he handed Lagune Chaffery's letter. He glanced at the little man ever and again to see if he had come to the personal portion, and for the rest of the time occupied himself with an envious inventory of the writing appointments about him. No doubt the boy with the big ears had had the same sort of thing ... When Lagune came to the question of his real identity he blew out his cheeks in the most astonishing way, but made no other sign. "Dear, dear!" he said at last. "My bankers!" He looked at Lewisham with the exaggerated mildness of his spectacled eye. "What do you think it means?" he asked. "Has he gone mad? We have been conducting some experiments involving--considerable mental strain. He and I and a lady. Hypnotic--" "I should look at my cheque-book if I were you." Lagune produced some keys and got out his cheque book. He turned over the counterfoils. "There's nothing wrong here," he said, and handed the book to Lewisham. "Um," said Lewisham. "I suppose this--I say, is _this_ right?" He handed back the book to Lagune, open at the blank counterfoil of a cheque that had been removed. Lagune stared and passed his hand over his forehead in a confused way. "I can't see this," he said. Lewisham had never heard of post hypnotic suggestion and he stood incredulous. "You can't see that?" he said. "What nonsense!" "I can't see it," repeated Lagune. For some seconds Lewisham could not get away from stupid repetitions of his inquiry. Then he hit upon a collateral proof. "But look here! Can you see _this_ counterfoil?" "Plainly," said Lagune. "Can you read the number?" "Five thousand two hundred and seventy-nine." "Well, and this?" "Five thousand two hundred and eighty-one." "Well--where's five thousand two hundred and eighty?" Lagune began to look uncomfortable. "Surely," he said, "he has not--Will you read it out--the cheque, the counterfoil I mean, that I am unable to see?" "It's blank," said Lewisham with an irresistible grin. "Surely," said Lagune, and the discomfort of his expression deepened. "Do you mind if I call in a servant to confirm--?"
