Nobody was able to answer this.
“If we’re smart enough we’ll find out,” said Katherine, waving her long arms. She was as keen on the scent of the mysterious Dark of the Moon Society as a hound after a stag.
That night darkness had hardly fallen when the Captain, Slim and the Bottomless Pitt complained of being utterly tired out and announced their intention of going to bed.
“What made you so tired, boys?” asked Mrs. Evans solicitously. “Are we expecting you young people to do too much? I don’t want you to go home worn out.”
“Oh, it was probably from running up and down the path so often with the boards for the dock,” said the Captain. “That’s all.” He yawned widely behind 162 his hand. “We’re not doing too much every day, really we aren’t. You mustn’t feel anxious.”
Mrs. Evans made a mental resolve to see that the boys and girls all had a definite rest hour each day.
Katherine’s thoughts went into a widely different channel. At the first mention of going to bed before the others she became suspicious, and, looking closely, she was positive that the Captain’s yawn was feigned. Lying on her back on the sand so that her head was behind Sahwah and Gladys she whispered very quietly, “D. M. S. meeting.” Gladys and Sahwah squeezed her arm to let her know they understood and as soon as the three boys had started up the hill they rose also, saying they were going up on the Council Rock. Hinpoha rose and followed them; Migwan and Nakwisi apparently did not catch on, and remained where they were.
There was no time to follow the boys. The girls must be in the cave before the Sandwiches got there to be able to overhear anything. Taking a short cut, they came out on the bluff just above the cave. They could hear the boys stopping for a drink at the spring on the other side of the island.
“How’ll we get down?” asked Gladys in a whisper.
“Crawl down the face of the cliff,” said Sahwah. “And we’ll probably skin our whole mortal frames doing it.”
