Read the passage from animal farm.

the animals were thoroughly frightened. it seemed to them as though snowball were some kind of invisible influence, pervading the air about them and menacing them with all kinds of dangers. in the evening squealer called them together, and with an alarmed expression on his face told them that he had some serious news to report.

"comrades! " cried squealer, making little nervous skips, "a most terrible thing has been discovered. snowball has sold himself to frederick of pinchfield farm, who is even now plotting to attack us and take our farm away from us! snowball is to act as his guide when the attack begins. but there is worse than that. we had thought that snowball's rebellion was caused simply by his vanity and ambition. but we were wrong, comrades. do you know what the real reason was? snowball was in league with jones from the very start! he was jones's secret agent all the time. it has all been proved by documents which he left behind him and which we have only just discovered. to my mind this explains a great deal, comrades. did we not see for ourselves how he attempted—fortunately without success—to get us defeated and destroyed at the battle of the cowshed? "
