James Barham

A millionaire gun manufacturer and collector of ancient weapons who lives on a lonely island upriver from Gotham City in a medieval castle that he had transported from Europe stone by stone, When Barham is found murdered in August 1957, there are four likely suspects: Jay Sanderson, a gun smuggler and former racketeer: Adam Barham, the dead man's cousin and only heir; John Gorley, a businessman whom Barham had accused of fraud; and Robert Cray, vice-president of the Barham Gun Company. Batman ultimately proves that Cray committed the murder to conceal a large embezzlement, and he and Robin take the killer into custody.
