Monk and Natalie showed up first at the residence Charlie shared with his friend the next evening. All around there were large pieces of paper with equations on them. The mathematician absent mindedly let them in and continued with his work.

"Give me an eraser" Adrian told his assistant. The crooked equations and hastily written numbers were a torment to the sleuth.

"Why?"

"It's too messy" he answered as he pointed to one of the sheets of paper; Natalie glared at him. "I'll have it rewritten before he notices." For the sleuth, Charlie's scribbles were unbearable to look at. It didn't make sense to him how anyone could work like this.

Charlie went to refer to it justbefore Monk had finished erasing. He noticed that almost everything he had written on that sheet was gone.

"What happened to the equations I had here?" He picked up the paper in disbelief.

"I erased them"

"Why?" Charlie had been working on stuff that could be the key to figuring what type of work that might have gotten Hans killed. "I needed them!" This upset interrupted his train of thought.

Just then, Don knocked on the door, and Natalie let him in, when she verified who it was.

"What's going on?" the agent asked. He had heard Charlie yelling.

"He erased my equations!" Charlie's face was red with anger, and frustration. Deep, dark circles surrounded his eyes. Don recognized the signs of overwork in his brother.

"They weren't straight" Monk said with a straight face, thinking that the others would agree to his logic.

"Easy buddy…" Don calmed his brother as he glared at the sleuth. The agent hated it when his younger brother was upset or neglected to take care of himself because of math. "When was the last time you ate?"

"Yesterday morning" Charlie said.

"I'll go see what's in the fridge" Natalie said as she gave Monk a look.
