'Had you an English lady and gentleman, father and daughter, arrive on that day?'
'I had. Mr. and Miss White. The man was clean shaven, about forty-five years old.'
'This is the portrait of his daughter.'

Captain Hampton uttered an exclamation of satisfaction. Here then was the first absolute proof that his theory was correct, and that there really existed a double of Dorothy, and the evidence of this clerk would in itself go far to disprove the charge against her.
'How long did they stay here?' the detective asked.
The clerk turned to the ledger. 'Two days. They left on the evening of the sixth. They were charged the full day.'
'How did they go?'
'By carriage. Here is the charge—a dollar and a half.'
