Young Holliday, on his side, returned the gaze, amazed and puzzled by the medical student's odd language and manners.

It must have been a strong likeness, or I should certainly not have found it out, for I am naturally slow at detecting resemblances between faces.
"You have saved my life," said the strange man, still looking hard in Arthur's face, still holding tightly by his hand.
