"The woman in the blue dress," cried Tom. "Let me go, sir! let me go!"
"You must be dreaming, Tom," said Garden, his heart beating high with exultation. "Keep still, keep still! Remember you have promised to obey me implicitly."
"I saw her, I tell you!" cried Tom, shaking all over, but ceasing to struggle. "And now she has disappeared!"
"As she did on the night of the murder?"
"Yes, as she did then."
"But you saw her again?"
"Yes, I saw her again."
"But not in the same spot?"
"No," said Tom, turning in another direction. "This way."
He walked on fifty or sixty yards, and Garden, holding his arm more lightly, accompanied him.
