“He was living in Vienna under the name of Klein; living extravagantly on the proceeds of the Lefarge business. He belonged to a very vicious circle, amidst whom Gyde became implicated, and he was in low water financially. “Klein looked at Gyde, and saw that here was another chance of playing the old comedy of masks and faces. For Gyde’s face and figure lent themselves entirely to the trick. “He obtained a hold over Gyde and blackmailed him to a considerable amount, but this did not satisfy him. “His hatred of the rich and well-to-do and respected had to be satiated. “He made a bust of Gyde and his face, he studied him profoundly. He could reproduce his handwriting with absolute and marvellous precision, and his voice. “The bust was made in London; he took rooms in Howland Street, broke up the bust and came to Cumberland. “Took the Cottage on the Fells and awaited the coming of Sir Anthony. “Sir Anthony called upon him, as we have seen. “Klein stunned him with a sandbag, stripped him and decapitated him; dipped the head in a solution of chlorine which shrunk the skin and preserved it, placed the head in a black leather bag, dressed himself in his victim’s clothes, assumed his face and personality, dressed his victim in his own clothes and departed. “We know the rest. But one or two points may be made clearer. “On his arrival in London the supposed Gyde went to his bedroom. There was one weak point about the mask. Its prolonged use caused insufferable torment to the wearer, on account of the skin irritation it caused. “He had removed the mask for a moment when Leloir, who had left the room, returned, and saw reflected in a looking-glass his master removing his own face. Klein, hearing the footstep of Leloir, turned. “The expression on Klein’s face at that moment is preserved for us in the retinal photograph taken from the eye of the valet, who, beholding this monstrosity, gave vent to the awful cry heard by the secretary and fell dead. “Klein, in his hurry and the confusion caused by this incident, collected all the jewellery he could find. Having no immediate plan he thought it safest to leave his victim’s head behind him, trusting it would not be discovered for some time. He passed the night at Howland Street, going there disguised as Gyde. Next morning, early, under the same disguise, he withdrew the jewels at the bank and cashed the cheque at the jewellers. It was a cheque he had found in the pocket of his victim, and he cashed it, not so much for the money as to foul his traces and prove to the police, by extra evidence, the existence of Gyde. “Then he destroyed the mask and became Klein again, taking the house in St Ann’s Road, and moving in there with a few sticks of furniture hastily bought. “Mr Goldberg’s murder followed. “Then this gentleman, Mr Hellier, saw him and followed him. And Klein suspected that he was at last suspected. “He determined to disguise himself. How? Simply by becoming his own age.
