In a library, there are four friends - Mike, Jane, Peter, and Olivia. Mike witnesses Jane placing her favorite book on a shelf near the entrance before leaving for lunch. During her absence, Peter finds the book and moves it to a table at the back of the library. Later, Olivia comes across the book and returns it to its original spot near the entrance. Where does Mike think Jane's book is when she returns from lunch? Provide a very short response.
Mike believes Jane's book is still on the shelf near the entrance because he saw her place it there before she left for lunch. He is unaware of the actions taken by Peter and Olivia, who moved the book and then returned it to its original spot, respectively. Therefore, from Mike's perspective, the book has not been moved.
