Would he repeat it? We both watched breathlessly, as I headed the machine in his direction.
Yes!
Again the light spoke in the “longs” and “shorts” of the Morse code, which both Roseye and I could understand.
Together we read it.
“Return in an hour,” he signalled.
Why? I wondered. What could have occurred?
Somehow, by the appearance of his light, I thought he must be signalling in secret, and not in the open.
He would expect some acknowledgment from me, telling him that I understood.
Therefore I elevated our searchlight so as to shine upward, instead of below. Then, touching the lever, a long beam of white light shot skyward for a second.
Afterwards I shut it off, and made straight away due southward by the compass, greatly puzzled.
