Keep Your Readers Reading - The secrets to Pacing successfully

Project: Losing something then finding it
Breakfast was nice, Igor thought as he was entering his room. Maybe he could do some work before the council meeting. There is a book he stole from the library, "Letter to the Economy of 346 by Neven Fisher". The prince smiled just thinking about takeing a read about another of Neven's work. He casually approached his bedroom desk and put his hand in a hidden compartment of its drawer.
There was nothing. There was NOTHING! Keys to his office were gone! Nobody was supposed to have these keys. And there were the library keys attached to them that he was not supposed to have.
Somebody must have entered his room. Somebody stole it. Found his secrets. He will be exposed. His work will be found. He will be judged. He will be hated! His heart beat quickly. His breath was gone. He started choking. Asthma. He needed his inhaler. He ran. Stumbled at the night stand. Took the damned thing. Breath in, breath out. Three times. He hopes nobody hears him.
Was he sitting on something, something in his pocket? Keys... They were with him this whole time. He took them before going to breakfast. He is an idiot.
