The Snare by Rafael Sabatini

At once, as he sat there, his elbows on the table, his head in his hands, he found himself surrounded by those three, against each of whom he had sinned under the spell of the jealousy that had blinded him and led him by the nose.

His wife put an arm about his neck in mute comfort of a grief of which she only understood the half - for of the heavier and more desperate part of his guilt she was still in ignorance. Sylvia spoke to him kindly words of encouragement where no encouragement could avail. But what moved him most was the touch of Tremayne's hand upon his shoulder, and Tremayne's voice bidding him brace himself to face the situation and count upon them to stand by him to the end.
