He could see their faces distinctly in profile. They were of the classic Coptic type which so persistently reproduces the features of the old Egyptians as we see them outlined in the wall-paintings of the temples and the half-mutilated carvings and statues. The window of the study was open, but the door was shut; so was the door of his own room, but for all that he distinctly heard the man say to the woman in Coptic, which, curiously enough, sounded as familiar to his ears as the faces seemed to his eyes:

"Neb-Anat, it is gone! These heathen ravishers have not been content with stealing the body of our Queen from its sacred resting-place and bringing it here, whither we have traced it with so much labour. See, it has been stolen again; hidden, no doubt, so that the servants of the King could not find it. It may be that even we have been suspected and watched, in spite of all our care. Yet it must be found, or the doom that may not be revoked will be ours."

"Even so, Pent-Ah," replied the woman in a soft, musical voice which well suited the comeliness of her face; "but though the priceless treasure has been taken from its casket, it cannot have been carried out of the house, for you know that every approach has been watched closely since it was brought here. Come, in this house it must be, and to find it is our task. Every one is asleep; take off thy shoes and let us search."

She took off her own shoes as she spoke, and he saw the man do the same. Then, as the man opened the door and they passed out of the study, the picture vanished from the mirror.

Amazement at what he had seen and heard—the disappearance of the Mummy, the presence of the man and woman, evidently charged with what they believed to be the sacred mission of stealing it back again, and their evident purpose of searching the house for it—instantly gave place to a quick thrill of fear.

His daughter's bedroom was on the same floor as the study, only a couple of doors away round the corner of the landing. These people would search every room. What if she had not locked her door securely, or if they had some means of opening it? She was the living image of the dead Nitocris. He did not dare to think of what might happen to her. Would these new-found, strangely-given powers of his suffice to protect her? If not, he would have but little use for them, since she was his nearest and dearest on earth.

He pulled his stockings over the pants of his pyjamas and put on his velvet working jacket, forgetting for the moment that, if these things were true, it would be perfectly easy for him to make himself invisible to beings in the ordinary world of three dimensions. Then he turned out the light, opened the door very softly, and crept downstairs.

Yes, what he had seen was true. He heard the soft, shuffling patter of stockinged feet along the landing, though he could see nothing in the dark. A door opened gently. His sense of location told him that it was the door of the spare bedroom next but one to the study. He felt his way silently and softly along the wall, and as he did so his hand touched the electric switch. Should he turn the light on and alarm the house? Whoever was there had "broken and entered" after midnight, and was therefore outside the law. No, he would not do that. If what he had seen was true, the intruders believed that their mission was a sacred one. No doubt the man was armed, and perhaps the woman also, and what would a knife-stab mean to them on such a desperate quest?

As these thoughts ran at lightning speed through his mind, he saw a faint glow inside the room. He crept forward and looked round the side of the doorway. The man had a little electric lamp in his hand and was flashing the slender rays all over the room. He drew his head back quickly as he heard him say:

"There is nothing here, Anat. Come, let us try the next room. Neither lock nor bolt nor even human life must stand in the way of our search now that we have begun it!"
