“Ah,” replied the sceptical traveller, “but you don’t know how much of the old legend may have been made up from the old figures. Besides, it isn’t the only old legend. Fanshaw, here, who is fond of such things, will tell you there are other versions of the tale, and much more horrible ones. One story credits my unfortunate ancestor with having had the Spaniard cut in two; and that will fit the pretty picture also. Another obligingly credits our family with the possession of a tower full of snakes and explains those little, wriggly things in that way. And a third theory supposes the crooked line on the ship to be a conventionalized thunderbolt; but that alone, if seriously examined, would show what a very little way these unhappy coincidences really go.”
“Why, how do you mean?” asked Fanshaw.
“It so happens,” replied his host coolly, “that there was no thunder and lightning at all in the two or three shipwrecks I know of in our family.”
“Oh!” said Father Brown, and jumped down from the little table.
There was another silence in which they heard the continuous murmur of the river; then Fanshaw said, in a doubtful and perhaps disappointed tone: “Then you don’t think there is anything in the tales of the tower in flames?”
“There are the tales, of course,” said the Admiral, shrugging his shoulders; “and some of them, I don’t deny, on evidence as decent as one ever gets for such things. Someone saw a blaze hereabout, don’t you know, as he walked home through a wood; someone keeping sheep on the uplands inland thought he saw a flame hovering over Pendragon Tower. Well, a damp dab of mud like this confounded island seems the last place where one would think of fires.”
“What is that fire over there?” asked Father Brown with a gentle suddenness, pointing to the woods on the left river-bank. They were all thrown a little off their balance, and the more fanciful Fanshaw had even some difficulty in recovering his, as they saw a long, thin stream of blue smoke ascending silently into the end of the evening light.
Then Pendragon broke into a scornful laugh again. “Gipsies!” he said; “they’ve been camping about here for about a week. Gentlemen, you want your dinner,” and he turned as if to enter the house.
But the antiquarian superstition in Fanshaw was still quivering, and he said hastily: “But, Admiral, what’s that hissing noise quite near the island? It’s very like fire.”
“It’s more like what it is,” said the Admiral, laughing as he led the way; “it’s only some canoe going by.”
