How did Hari Singh steal the money that Anil got from selling his book to a publisher?

Ans. Hari Singh saw with his own eyes how Anil tucked the bundle of money under the mattress of his bed. When Anil was asleep, Had Singh crept up to the bed. He slid his hand under the mattress and drew the money out of the bundle without making a sound. Anil sighed in his sleep and turned on his side, towards him. Han Singh got startled and quickly came out of the room.
