"What did you sell that brought 23 centimes?" asked the colonel with a scrutinizing gaze.
"Are you sure that 23 meant centimes?"
The man's face paled, and for the first time he hesitated to reply promptly. The colonel gave him no time to collect his thoughts.
"What does the X stand for following 23?"
"Ten."
"Ten what?"
"The profit I made."
"On what? On the 8.90?"
"Yes," was the relieved reply.
"Put him under guard," ordered the colonel.
