The Bigamist by Ethel Mills

It seemed as though Arnott, after years of indifference, had abruptly awoke to his duties as a father. He began to take a quite extraordinary interest in his children. Exercise in the car ceased to be an astounding treat and became an almost daily custom. He even penetrated into the nursery, usually when the children were in bed. He bought sweets for them, and chose this hour for presenting his gifts.

Pamela looked on, puzzled. She refrained from any comment; she was on the whole pleased; but she was not confident as to the staying qualities of this sudden show of interest; and she awaited developments with a doubt as to his entire sincerity in the new pose. Not for a long time did she connect the change in his attitude with the presence of Miss Maitland in the nursery. It spoke eloquently for Arnott's discretion that Pamela was so blind to his intimacy with her children's governess; had he been at all indiscreet in his conduct before the children they would have carried tales. It was in order to avoid the disconcerting evidence of sharp eyes and small ears that he usually visited the nursery when they were in bed.
