"About the fly I know nothing," said the secretary positively, "but this scent is not to be had in England, and Sir Charles's clothes could only have gathered the fragrance from mine. If Inspector Tenson suspects me----" "No, no, no!" interrupted Halliday quickly. "I assure you that he does not." "He would if you told him of our meeting," retorted Penn as they passed into Piccadilly Circus, "and as I don't like even a suspicion to rest on me, Mr. Halliday--for my good name is my fortune--I shall go and see him and explain the whole circumstance. Indeed, if he wishes it, I shall give him the bottle which my cousin sent me from Sumatra, and never shall I use the scent again. I do not like these injurious suspicions." "Don't make a mountain out of a mole-hill," said Dan, drily; "if I have hurt your feelings, I apologize." "I accept your apology only on condition that you accept my explanation." Dan inwardly chuckled at Penn's dignity, but replied, readily enough. "Oh, yes, for if I did not accept your explanation I should not make any apology. You are probably right since the scent must have got on to Sir Charles's clothes from your own. The clue--as we took it to be--has ended in smoke." "But don't you think that I should see Inspector Tenson and explain?" "There is no need," Dan assured him, soothingly. "If the Inspector says anything about the scent, I shall explain; and, after all, it was I who suggested the perfume as a clue." "Would you like what is left of the bottle?" asked Penn, pacified by the very frank apology of the other. "No, thanks, I never use perfumes. I hate them." "So did Sir Charles," mused Penn, and eyeing Dan with a lack-lustre gaze. "I wonder he did not suspect me of liking them. If he had come upon me scented in this manner, he would have kicked me out." "It is to be hoped Lord Curberry has not the same dislike," said Dan, who having learned all he wished, desired to escape from such boring society. "No, he has not," said Penn with great simplicity; "he is very kind to me. I suppose he will marry Miss Moon." "Then you suppose wrong. He will not," snapped Halliday roughly. "He loves her devotedly," insisted the secretary, and with a glint of malice in his pale-colored eyes. "Good-day," rejoined Dan shortly, as he did not wish to argue the matter. He turned into Regent Street--for by this time they had crossed the Circus--when Penn ran after him and seized his arm. "Is there any chance of the woman who killed Sir Charles being found?" "No," replied Dan, halting for a moment. "Why?" "Because Sir Charles was good to me, and I should like his death to be avenged. That is only natural. Surely the police will search." "They are searching, Mr. Penn, and can discover nothing." "Perhaps Lord Curberry may hunt for this woman. I shall ask him to, and as he loves Miss Moon so devotedly, he will try to learn the truth."
