My wife, who up until then had been so calm and collected, began to emit a sort of chortle, intermittent at first but soon growing in frequency before developing into the full-fledged so-called “laughter.” They call it laughter, but there was nothing happy or cheerful about it. It sounded as though she was trying to stifle a laugh as it welled up, but for the life of her she couldn’t hold back, and no matter how much she tried, her brain was unable to overcome the involuntary physical reaction—that’s what kind of laugh it was. An unspeakably sinister laugh, as if at some sick joke.
