But an angry glance from her companion dispelled the passing softness. "You shall both be safe so long as you obey me," she said. "Duncan, I will tell you now, is safe in the hospital. At a word from me Meg will fetch him away. At present he is well tended, with kind doctors and nurses to give him everything he wants, and he will soon be well, for it is only a bad cold he has taken."

Elsie sank back with a sigh of relief. She pictured poor little Duncan lying on a soft white bed, with kind people bending over him, as Mrs. MacDougall had done when she was sick. It brought a great feeling of peace to her mind. She would do anything they wished her, to be sure that Duncan was safe. The only thing that troubled her now was whether Mrs. Donaldson had spoken truly; for children are quick to find out who may be trusted, and Elsie had no faith in either of these two people.

Elsie believed herself that Meg would take Duncan if it depended at all upon her, for although her behaviour had been strange, Elsie could not forget her kindness in the night, when there had been no one near. Nothing would ever make Elsie think that it was not true and genuine. It was, indeed, her faith in Meg's goodness that was her one consolation. She clung to that much more than to all Mrs. Donaldson's statements.

Presently the train stopped. "Uncle William" came, and sat very close to Elsie on one side, Mrs. Donaldson on the other, and each took one of her hands with an appearance of great affection. Elsie sat perfectly still. She had no intention of making any more disturbance. If Duncan's safety depended on her being quiet, no mouse should be more quiet than she was.

Mrs. Donaldson seemed pleased. "I see you are a sensible little girl," she said. "Now, you must mind what I tell you. Remember, I shall not tell you when I send the message, but directly you are troublesome it will go. I may not tell you till the week is gone; but you may feel quite sure that it will not be sent unless you disobey or are naughty. Do you quite understand?"

Elsie replied that she did, and Mrs. Donaldson continued—

"Do not mention Duncan again, not even to me when I am quite alone. He is always Donald."

"I will not forget," Elsie replied.

"And you will have no Uncle William when you get to London. This gentleman is your Grandpapa Donaldson. Now, I have seen that you are clever enough when you choose. Do not forget."

The train had again started on its way, and was rushing along at a tremendous rate, being an express. Mrs. Donaldson had got Elsie's hand in hers, and had kept the child's attention fixed upon herself. The gentleman was now seated in another corner. When Elsie next turned her head towards him, he had utterly changed. In the place of a dark-looking man with a small moustache was an elderly gentleman, with a face quite bare, except for some small grey whiskers and a bald head. He was lounging back most unconcernedly in the carriage, looking through his spectacles at the objects so swiftly flying past them.
