Answer:
The author use foreshadowing to build suspense in the story by signaling the readers of the antagonist's, Mr. Horrocks, intentions to kill Mr. Raut. According to the text, it states, "Was he deluding himself with his own fancies, or had Horrocks actually held him back in the way of the train? Had he just been within an ace of being murdered?". This tells the readers that the author was trying to convey that Mr. Horrocks planned to kill Mr. Raut, however his first attempt failed. This builds up tension and suspense to the story for the readers does not know what Mr. Horrock's next attempt be.
Another example, "But all the same, what on earth did Horrocks mean about “white as death” and “red as sin?” Coincidence, perhaps?". This tells the readers that the author was trying to emphasize what Mr. Horrocks said. This also foreshadows the death of Mr. Raut and the sin that Mr. Horrocks will soon to commit. As the story progresses, Mr. Raut finally realizes the intentions of Mr. Horrocks craving to kill him. Based on what I read, " “Three hundred centigrade, mind!” said Horrocks. “It will boil the blood out of you in no time.” “Eigh?” said Raut, and turned.". This tells the readers that Mr. Horrocks was making his second attempt to kill Mr. Raut. The phrase, "It will boil the blood out of you in no time", foreshadows the plan to burn Mr. Raut to death.
