Those who expected to see Margolo make immediate war upon Red McGuirk were disappointed. Never had the gangster been so quiet. With his inactivity, the percentage of crime in the city dropped until a pedestrian could stroll the streets with comparative safety. The general public reached the conclusion that Margolo’s recent trial had shaken his nerve. Not so the police.

“It’s only the calm before the storm,” observed Captain Henessey. “When Margolo gets under way he’ll raise more hell than ever. I’ve seen these birds before and I know.”

Nightly, Dave Cates stood before the microphone, talking to the world. No more attempts were made upon his life, but he wasn’t fooled by that. Eventually the gunmen would seek him out again. He’d have to get them before they got him.

Each night after the broadcast he went in search of Big Ed Margolo. Everywhere the gangster went, he was followed by a little man with pulled-down cap and turned-up coat collar.

Cates’ size alone probably saved him. The torpedoes who “covered” Margolo never paid any attention to him. It is doubtful if they noticed him.

One evening, Margolo came out of his apartment and summoned a taxi. Dave Cates, lurking in the shadows half a block away, took the next taxi along. Margolo drove to an old house out on River Street, far from the business district. When he came out of the house, he tried a key in the door. Apparently satisfied, he rejoined his companions and the taxi drove off.

Dave Cates had a sudden hunch. He took the number of the house, and ordered his driver back to the city. Two blocks from police headquarters he alighted. Not even a taxi driver should know that he was in any way connected with the police.

With all the enthusiasm of a terrier puppy he burst in upon Captain Henessey.

“Margolo has just rented a house out on River Street,” Cates said rapidly. “Don’t know what he’s going to do, but it’s a cinch he didn’t rent the place to live in. Now listen, captain. There’s an old vacant garage out back of the place. Can’t I have a microphone put up in there?”
