Their mother dead early, their father uninterested, the Wallace twins had grown up in the care of an ever-changing succession of housekeepers, with no one close but one another. Fortunately, they had always been content with that company and had almost never been apart. Now, Adam has met someone and, without preamble, married her. Robert is bereft, and the stage is set for a Christmas nobody is likely to forget. A short story from our Nibs literary line.
