"The police know nothing whatever of this man's activities. Coffran is old and wise. His memory is remarkable, and his resources are many.

"So be alert. Be careful. Remember all you see, and report everything. We are on the verge of important discoveries. Three men are missing. The Shadow intends to find out where they are."

Harry Vincent left the office with the address of Isaac Coffran tucked away in his vest pocket. He was sober as he went down in the elevator. Fellows's words had been impressive; never before had the insurance broker talked so thoroughly. A tremendous crisis must have arisen, for The Shadow's detail man had exhibited unprecedented activity.

Master minds were engaged in some uncommon crime. The Shadow was exerting all his power to defeat them. The Shadow would need many eyes to-night.

CHAPTER X. INTO THE SNARE

The house of Isaac Coffran was an old brick building in an obscure street on the East Side. It seemed strangely deserted to Bruce Duncan as he rang the bell alongside the massive door.

If his uncle's friend had not assured him that he should come at eight o'clock Thursday evening, Bruce would have decided that the house was unoccupied. For all the windows at the front were closed with iron shutters.

Even now he hesitated. He had rung the bell three times, yet there had been no response from within.

Still, it was exactly eight o'clock. It would be best to wait.

The door opened suddenly. Bruce started backward as he faced a huge, dull-faced man whose features were marred by a livid scar across one cheek. The fellow was considerably over six feet in height, and his frame was powerful.
