Eric Darrell was gradually applying this former principle to the case in question.

Perhaps Joe might be innocent, and this cloud hanging over him be the result of circumstantial evidence.

At any rate the detective hoped so.

He looked at his watch mechanically.

Just now the thought came into his head that he must find out all about Joe before another night had spread its mantle over the city.

The time dragged along.

He had some work to do in his office, and this consumed something like an hour.

Then he made his way slowly in the direction of Twenty-seventh Street.

It was about four when he came in sight of the house around which clustered so much that was mysterious.

Sauntering along, he kept watch for Joe, feeling almost sure the other would come.
