the listener?

Can anyone help me to find a story by O Henry which my mother read as a child (she is now 80) - she believes it was called "The Listener" and would dearly love to read it again. I have been unable to find anything with this title and wondered whether anyone would recognise the tale of a person who hears the goings on of others. Further update from elderly mother now suggests the story was about people who thought they were in some kind of confessional but they didn't realise nobody was there? I would be so grateful if anyone could help. Many thanks

The Listener is a short novel by Taylor Caldwell and is available online at several book sites including Amazon.
