Captain Jack Crocker

First Officer on the S.S. Rock of Gibraltar.

He was a very tall young man, golden-moustached, blue-eyed, with a skin which had been burned by tropical suns, and a springy step, which showed that the huge frame was as active as it was strong.
A very formidable person. Strong as a lion — witness the blow that bent that poker! Six foot three in height, active as a squirrel, dexterous with his fingers, finally, remarkably quick-witted, for this whole ingenious story is of his concoction. Yes, Watson, we have come upon the handiwork of a very remarkable individual.

His record was magnificent. There was not an officer in the fleet to touch him. As to his character, he was reliable on duty but a wild, desperate fellow off the deck of his ship — hotheaded, excitable, but loyal, honest, and kind-hearted.
