It wasn't just that his signature was difficult to read.

She had seen inscrutable handwriting before. It was that it looked like some other word than his name. Most vague signatures were a large capital followed by a line of varying straightness or a nice friendly scribble. His was loops, squiggles, the random right angle that could have formed letters but didn't. It seemed to signify more than a name or a mark of acknowledgement. It was a mark, it did something other than just being on the paper.

Something dark, something sinister and out of the ordinary. He was clearly the most evil CPA she had ever encountered.
