That night nothing happened - neither did anything happen the next night or the next - but on the fourth night there was great excitement. A light flashed in the tower at midnight! There it was, as plain as could be!
A Strange Discovery
It was Peggy who first saw the light flashing in the tower of the Old House. Mike had had the first watch that night, and Peggy had come up from her room about one minute before midnight to take her turn at watching.
She whispered a few words to Mike, and took her seat by the window.
“There hasn’t been a sign of anything,” Mike said in a low voice, and he threw off his dressing-gown to get into bed. “This is the fourth night we’ve watched - it’s a bit boring, I think. Do you suppose that...”
But just at that moment Peggy gave such a loud squeal that Mike jumped. “Mike! Oooh, look! Mike! There’s a light in the tower. It’s just come, this very moment!”
Mike ran to the window, almost falling over a chair on the way. Jack awoke at the noise.
“Yes!” said Mike. “It’s a light! Jack! Jack! Come and look!”
Jack jumped out of bed and ran to the window. Sure enough, there was a light in the distant tower - a light that dipped and flashed and dipped and flashed.
“They are signalling,” said Jack, in excitement. “The boat must be standing out to sea watching for the signal right beyond that rocky crag we sailed round.”
