Astro stared in surprise. It was the same word, evidently, that he had found on the ashes of Mrs. Burbank's letter. He turned to the nurse, who apparently had noticed nothing unusual.
"What does she mean by that?" he asked.
"Oh, that 'Kellem, kellem'? Why, I don't know, I'm sure, sir. I fancy it's one of the games they play with Colonel Trevellian. He often comes in here for a romp with the kiddies, and they seem to be fond of him. I've heard Agatha say that before; but, lord! I never thought to wonder about it. It is funny, isn't it?"
Again the child reached out her arms and repeated the words, "Kellem, kellem!"
"Did she ever play that particular game with her mother, nurse?"
"I don't remember, sir, I'm sure. I expect so, though. Seems to me, now I think of it, I did hear Mrs. Burbank trying to break Agatha of it; but no doubt I've got it mixed up."
Astro watched the children for some time; then, after kissing each of the chubby faces, went thoughtfully down-stairs.
He had no sooner reached the hall than the outer door opened, and Burbank entered with a serious expression on his face. He bowed and shook his head sadly.
"My misfortunes are all coming at once, it seems," he said. "My brother is dead, my wife missing. It's too much for me, and I'm afraid I'll have to call in the police and put them on the case. I can't stand it any longer; unless unless you have discovered some way of helping me," he added.
