The Witch of Prague by F. Marion Crawford

The Wanderer glanced at Unorna's face and saw the expression of relentless hatred which had settled upon her features. He neither understood it nor attempted to account for it. So far as he knew, Israel Kafka was mad, a man to be pitied, to be cared for, to be controlled perhaps, but assuredly not to be maltreated. Though the memories of the last half hour were confused and distorted, the Wanderer began to be aware that the young Hebrew had been made to suffer almost beyond the bounds of human endurance. So far as it was possible to judge, Israel Kafka's fault consisted in loving a woman who did not return his love, and his worst misdeed had been his sudden intrusion upon an interview in which the Wanderer could recall nothing which might not have been repeated to the whole world with impunity.

During the last month he had lived a life of bodily and mental indolence, in which all his keenest perceptions and strongest instincts had been lulled into a semi-dormant state. Unknown to himself, the mainspring of all thought and action had been taken out of his existence together with the very memory of it. For years he had lived and moved and wandered over the earth in obedience to one dominant idea. By a magic of which he knew nothing that idea had been annihilated, temporarily, if not for ever, and the immediate consequence had been the cessation of all interest and of all desire for individual action. The suspension of all anxiety, restlessness and mental suffering had benefited the physical man though it had reduced the intelligence to a state bordering upon total apathy.
