Haasberg now feared the worst. He blamed himself terribly for not having made more certain of the mysterious visitor's identity. He had not yet come to the point of accusing his brother-in-law in his mind of a conspiracy to steal the necklace, but frankly, at this stage, he did not know what to think. Saunders's conduct had--to say the least--been throughout extremely puzzling. Why had he elected to spend the night in Paris, when all arrangements had been made for him and his wife to travel straight through? Who was the mysterious visitor with the walrus moustache, vaguely referred to by both Arthur and Mary as "old Pasquier"? And above all why had Arthur withdrawn the necklace from the hotel strong-room where it was quite safe, and, with it in his pocket, walked about the streets of Paris at that hour of the night? Haasberg was quite convinced that "old Pasquier" knew something about the whole affair, but, strangely enough, Mary persisted in asserting that he was quite harmless and an old friend of Arthur's who was beyond suspicion. When further pressed with questions, she declared that she had no idea where the man lodged, and that, in fact, she believed that he had left Paris the self-same evening _en route_ for Brussels, where he was settled in business. Enquiry amongst the personnel of the hotel revealed the fact that Captain Saunders's visitor had been seen by the hall porter when he came soon after half-past eight, and asked whether le Capitaine Saunders had finished dinner; his question being answered in the affirmative, he went upstairs, refusing to take the lift. Half an hour or so later he was seen by one of the waiters in the lounge hurriedly crossing the hall, and finally by the two boys in attendance at the swing doors when he went out of the hotel. All agreed that the man was very tall and thick-set, that he wore a heavy moustache and a pair of gold-rimmed spectacles. He had on a bowler hat and an overcoat with the collar pulled right up to his ears. The hall porter, who himself spoke English fairly well, was under the impression that the man was not English, although he made his enquiries in that language. In addition to all these investigations, the commissaire de police, on his second visit to the hotel, was able to assure Haasberg that all the commissariats in and around Paris had been communicated with by telephone so as to ascertain whether any man answering to Saunders's description had been injured during the night in a street accident, and taken in somewhere for shelter; also that a description of the necklace had already been sent round to all the Monts-de-Piété throughout the country. The police were also sharply on the lookout for the man with the walrus moustache, but so far without success.
