"And an ingenious one," he returned. "It was Cullen Mayle who taught it to us in the mess at Star Castle. For packing the cards or knapping the dice I never came across his equal. Yet we could never detect him, and in the end not a soul in the garrison would play with him for crooked pins."

"Cullen Mayle," said I; "that was Adam's son."

Clutterbuck had sunk into something of a reverie, and spoke rather to himself than to me.

"They were the strangest pair," he continued; "you would never take them for father and son, and I myself was always amazed to think there was any relationship between them. I have seen them sitting side by side on the settle in the kitchen of the 'Palace Inn' at Tresco. Adam, an old bulky fellow, with a mulberry face and yellow angry eyes, and his great hands and feet twisted out of all belief. His stories were all of wild doings on the Guinea coast. Cullen, on the other hand, was a stripling with a soft face like a girl's, exquisite in his dress, urbane in his manners. He had a gentle word and an attentive ear for each newcomer to the fire, and a white protesting hand for the oaths with which Adam salted his speech. Yet they were both of the same vindictive, turbulent spirit, only Cullen was the more dangerous.

"I have watched the gannets often through an afternoon in Hell Bay over at Brehar. They would circle high up in the air where no fish could see them, and then slant their wings and drop giddily with the splash of a stone upon their prey. They always put me in mind of Cullen Mayle. He struck mighty quick and out of the sky. I cannot remember, during all the ten years I lived at the Scillies, that any man crossed Cullen Mayle, though unwittingly, but some odd accident crippled him. He was the more dangerous of the pair. With Adam it was a word and a blow. With Cullen a word and another and another, and all of them soft, and the blow held over for a secret occasion. But it fell. If ever you come across Cullen Mayle, Berkeley, take care of your words and your deeds, for he strikes out of the sky and mighty quick."

This Clutterbuck said with an extreme earnestness, leaning forward to me as he spoke. And even now I can but put it down to his earnestness that a shiver took me at the words; for nothing was more unlikely than that I should ever come to grips with Cullen Mayle, and the next moment I answered Clutterbuck lightly.

"Yet he sat in the stocks in the end," said I, with as much indifference as I could counterfeit; for I was afraid lest any display of eagerness might close his lips. Lieutenant Clutterbuck, however, was hardly aware that he was being questioned. He laughed with a certain pleasure.

"Yes. A schooner, with a cargo of brandy, came ashore on Tresco. Cullen and the Tresco men saved the cargo and hid it away, and when the collector came over with his men from the Customs House upon St. Mary's, Cullen drove him back to his boats with a broken head. Cullen broke old Captain Hathaway's patience at the same time. Hathaway took off his silver spectacles at last and shut up his Diodorus Siculus with a bang; and so Cullen Mayle sat in the stocks before the Customs House on the Sunday morning. He left the islands that night. That was two years and a month ago."

"And what had Dick Parmiter to do with Cullen Mayle?" said I.

"Dick?" said he. "Oh, Dick was Cullen Mayle's henchman. But it seems that Dick has transferred his allegiance to----" And he stopped abruptly. His face soured as he stopped.
