How does the author use foreshadowing in Swimming Lessons?

Janette Turner Hospital from the Los Angeles Times Book Review notes that Mistry is imitative of Indian novelist Anita Desai in his depiction of sudden and grotesque incursions of violence into the community, but he has the habit of predictably and rather portentously foreshadowing these events with things like a splat of betel juice on a white cloth, which prefigures a murder, and a rat bludgeoned with a cricket bat, which foreshadows the bludgeoning of a starving servant.
