“Robert Galvin has been arrested for the murder of Zachary Mitchell.”

“What!” exclaimed Bob.

“Certainly. The Shadow has played into our hands,” Mallory went on. “It is well that we let Galvin live.”

“How did they come to get him?”

“Robert Galvin announced his name when he entered Mitchell’s apartment house. He was also seen to leave hurriedly.”

“That was me!” Bob informed.

“Certainly,” Mallory continued, “but the police don’t know that. Inspector Zull made the arrest. Galvin is in jail. Getting the third degree now, in all probability.”

Bob Maddox chuckled. This was the final touch!

THE gloom had thickened in the room; Mallory could scarcely see the faces of his companions now.

“Raise that shade higher,” he ordered. “We need more light, but we don’t want to turn on the electricity.”
