“That might be a flashlight!” Mr. Holloway said. “It’s certainly coming from Rabb Island or close to it.”
“Maybe Mr. Hatfield is trying to signal us! I know he had a flashlight in his pocket.”
“It looks like code,” Mr. Holloway declared as the signals again were seen. “Morse code. Can you read it, Dan?”
“No, but Brad can. He studied it in scouting last year.”
“Then get him! But be quick about it. Those flashes are becoming weaker.”
Requiring no urging, Dan darted up the stone steps two at a time, bursting into the Holloway kitchen.
“Come quick, Brad!” he urged. “Someone is signaling from Rabb Island in Morse code. We need you to read it.”
Not only Brad but all the Cubs poured out of the kitchen and ran down to the river.
The flashes of light still were visible from across the water.
“Can you make them out, Brad?” Mr. Holloway asked. “It’s important that we read the message. Mr. Hatfield and Chips may have run into trouble.”
