Narrator

Carl Brown, who has been ill, is told by gangster Jerry Buck that unless he pays him $100, his shop will be wrecked and he'll be killed.

So Carl goes to see Boston Blackie, and Blackie agrees to be with Carl the next day when the gangster comes for payment.

That night, however, Carl's friend, John Rainey, pulls a gun on Carl and announces that he is going to kill him.

Next morning, Carl is found at home, dead, without a mark on him.

Death is attributed to natural causes,

But Blackie is convinced Carl was murdered.

As we return to our story, Blackie and his friend, Mary Wesley, wait in the dead man's cleaning establishment for the appearance of a gangster.

Now back to Dick Calmer's Boston Blackie.

Enemy to those who make him an enemy.

Friend to those who have no friend.

Now back to Boston Blackie.

This has been a strange evening for Boston Blackie.

Three times by three different people, he's been called Mr. Peterkin.

But this is nothing compared to what happened shortly after.

When Mary walks into Brandon's jewelry store with a watch Blackie had bought there an hour earlier, she finds the owner dead.

When Blackie joins her in the store to start an investigation, they're both found there by the police.

And though Inspector Faraday sees no reason to hold Mary or Blackie for Brandon's murder, an insurance agent demands their immediate arrest.

As we return to our story, Robert Winston, the insurance agent, calls on a certain diamond dealer.

And now on to Dick Calmer as Boston Blackie.

Enemy to those who make him an enemy.
