But it was the talk of Sir Wade, especially when in his cups, which chiefly led his friends to deem him mad. In a rational age like the eighteenth century it was unwise for a man of learning to talk about wild sights and strange scenes under a Congo moon; of the gigantic walls and pillars of a forgotten city, crumbling and vine-grown, and of damp, silent, stone steps leading interminably down into the darkness of abysmal treasure-vaults and inconceivable catacombs. Especially was it unwise to rave of the living things that might haunt such a place; of creatures half of the jungle and half of the impiously aged city — fabulous creatures which even a Pliny might describe with scepticism; things that might have sprung up after the great apes had overrun the dying city with the walls and the pillars, the vaults and the weird carvings. Yet after he came home for the last time Sir Wade would speak of such matters with a shudderingly uncanny zest, mostly after his third glass at the Knight’s Head; boasting of what he had found in the jungle and of how he had dwelt among terrible ruins known only to him. And finally he had spoken of the living things in such a manner that he was taken to the madhouse. He had shewn little regret when shut into the barred room at Huntingdon, for his mind moved curiously. Ever since his son had commenced to grow out of infancy he had liked his home less and less, till at last he had seemed to dread it. The Knight’s Head had been his headquarters, and when he was confined he expressed some vague gratitude as if for protection. Three years later he died.
Wade Jermyn’s son Philip was a highly peculiar person. Despite a strong physical resemblance to his father, his appearance and conduct were in many particulars so coarse that he was universally shunned. Though he did not inherit the madness which was feared by some, he was densely stupid and given to brief periods of uncontrollable violence. In frame he was small, but intensely powerful, and was of incredible agility. Twelve years after succeeding to his title he married the daughter of his gamekeeper, a person said to be of gypsy extraction, but before his son was born joined the navy as a common sailor, completing the general disgust which his habits and mesalliance had begun. After the close of the American war he was heard of as a sailor on a merchantman in the African trade, having a kind of reputation for feats of strength and climbing, but finally disappearing one night as his ship lay off the Congo coast.
In the son of Sir Philip Jermyn the now accepted family peculiarity took a strange and fatal turn. Tall and fairly handsome, with a sort of weird Eastern grace despite certain slight oddities of proportion, Robert Jermyn began life as a scholar and investigator. It was he who first studied scientifically the vast collection of relics which his mad grandfather had brought from Africa, and who made the family name as celebrated in ethnology as in exploration. In 1815 Sir Robert married a daughter of the seventh Viscount Brightholme and was subsequently blessed with three children, the eldest and youngest of whom were never publicly seen on account of deformities in mind and body. Saddened by these family misfortunes, the scientist sought relief in work, and made two long expeditions in the interior of Africa. In 1849 his second son, Nevil, a singularly repellent person who seemed to combine the surliness of Philip Jermyn with the hauteur of the Brightholmes, ran away with a vulgar dancer, but was pardoned upon his return in the following year. He came back to Jermyn House a widower with an infant son, Alfred, who was one day to be the father of Arthur Jermyn.
Friends said that it was this series of griefs which unhinged the mind of Sir Robert Jermyn, yet it was probably merely a bit of African folklore which caused the disaster. The elderly scholar had been collecting legends of the Onga tribes near the field of his grandfather’s and his own explorations, hoping in some way to account for Sir Wade’s wild tales of a lost city peopled by strange hybrid creatures. A certain consistency in the strange papers of his ancestor suggested that the madman’s imagination might have been stimulated by native myths. On October 19, 1852, the explorer Samuel Seaton called at Jermyn House with a manuscript of notes collected among the Ongas, believing that certain legends of a grey city of white apes ruled by a white god might prove valuable to the ethnologist. In his conversation he probably supplied many additional details; the nature of which will never be known, since a hideous series of tragedies suddenly burst into being. When Sir Robert Jermyn emerged from his library he left behind the strangled corpse of the explorer, and before he could be restrained, had put an end to all three of his children; the two who were never seen, and the son who had run away. Nevil Jermyn died in the successful defence of his own two-year-old son, who had apparently been included in the old man’s madly murderous scheme. Sir Robert himself, after repeated attempts at suicide and a stubborn refusal to utter any articulate sound, died of apoplexy in the second year of his confinement.
