"I found it," said I, and this gave me a chance I had been wanting but hadn't quite known how to snatch. "I was rather worried over the responsibility. Of course you knew that we'd take care of your treasures."
"It's all my money, and—and just one other thing!" Biddy answered, with an odd little hesitation in her manner and a catch in her voice. "I should hate to have anybody open that bag. I'm thankful it's safe. With you, I know it's sacred. All the same, I'd like to have it, if you don't mind the bother."
"You oughtn't to carry the thing about with you, if it's so important," I scolded her. "Why not leave your secret treasure, whatever it is, and most of your money, in Cairo, when you come off on an expedition like this?"
"I don't know," she mumbled evasively. "I'm used to having this thing with me. I can't think how I forgot it under my pillow. I never have before. It isn't the sort of—of valuable one keeps in a bank. Monny embroidered the bag when she was a little girl. It was her first work. I taught her how to do it, and she gave it to me for a birthday present. I wouldn't lose it for the world."
"You shan't," I said soothingly. I had heard what I had been afraid to hear; but why should Biddy's trip be spoiled by another worry if I could shield her? We could not know that the oiled hand had been groping for that bag; and I resolved not to distress Brigit by putting the idea into her head at present. "Go to sleep again in peace, both of you," I went on. "All's well, since you are well. Probably some prowler has been sneaking round the kitchen-tent."
"Yes. The news of the lamb has gone forth!" said Biddy. "Good night!"
"Good night!" I answered.
Down went the tent flap, and hid the sparkle of eyes in starsheen, and mist of gold in wavering candle-light. We trusted that the two had crept back into their beds; but we did not return to ours. We took one of the camp lanterns and searched for footprints—those which were freshest after the rain. The rough grass growing sparsely out of the sandy earth was not favourable to such attempts, however; and even at dawn, when we looked again before the camp was stirring, we made no notable discoveries such as amateur detectives make, in books.
Our next expedition, as soon as light came, was to the town, where we inquired at the few hotels, and put questions to the police. Nobody answering the description of Bedr and his two companions had been seen in Medinet, and we had to go back to camp baffled.
There was our adventure; and when we reached Cairo by train, the mystery of the oiled hand was still unsolved.
