Then they asked what the visiting doctor had said, and what directions he had given about Marcello's treatment.
"I am sure it is he," said the Chief of Police when they were closeted in the Superintendent's office, five minutes later.

"I have studied his photograph every day for nearly three months.

Look at it." He produced a good-sized photograph of Marcello which had been taken about a year earlier, but was the most recent.

The Superintendent looked at it critically, and said it was not much like the patient.

The official objected that a man who was half dead of fever and had lain starving for weeks, heaven only knew where, could hardly be quite himself in appearance.
