The Bigamist by Ethel Mills

Dare lunched alone with Mrs Carruthers. He was a little unpunctual; but she waited for him, and they sat down as soon as he came in. She did not ply him with questions; she kept her curiosity within bounds until the meal was well advanced. He was strangely quiet and preoccupied. She did not know what to make of his dejected silence. Mysteries were worrying to Connie Carruthers' practical nature. It was the flavour of mystery which clung about the happenings next door that caused her, despite the warmth of her affection for Pamela, to avoid the house of late. She had the keen dislike of a healthy minded person for anything in the way of concealment. Discreet reticence was praiseworthy, but furtive silence bred distrust. His visit next door had, it seemed to her, given George Dare the air of a conspirator. Whatever shadow hung over the house had enveloped him in its gloom.

It was absurd in her opinion for a man to allow his feeling for a married woman to swamp him in this fashion; it betrayed a lack of dignity and self-respect.
