It was late one night, and the fire was dying down to a warm, comfortable glow while I perused my case notes and Holmes sedately smoked his pipe.

"And you knew he was lying about his profession from a simple handshake?" I asked, amazed.

"Yes Watson," Holmes replied, a smile playing about his lips. "Agricultural workers get very distinctive callouses on their hands. I noticed at once that Mr Whitmore's hands were smooth, realized that he had signed on recently, possibly secretly hired to murder. After that, it was a simple matter of paying close attention to all his actions."
