But I was not in the way of sleeping out in this early season with its cold, though, of course, it was always possible that one might be belated on the hills and have to make a night in the heather of it when hunting on Exmoor or the Brendons.

There was not much moon left now, either.
So I showed the note to Owen presently, and he puzzled over it, seeing that it could not have been sent for nothing.

At last we both thought that whoever wrote it, or had it written, knew that some attack would be made on us with the next moon, when it would be likely that we might be riding homeward by its light with no care against foes.

That might well be called "sleeping in the moonlight" as things were; and at all events we were warned in time.

The trouble to me was that it seemed to say that danger was not all past.
However, when there was no moon at all I forgot the letter for the time, no more trouble cropping up, and but for a chance word I think that it had not come into my mind again until we were out in the moonlight at some time.
