Lamont Cranston

Cranston's friend and companion, the lovely Margo Lane, is the only person who knows to whom the unseen voice belongs.

Today's story, Murder...

Okay, I'll report back to headquarters as soon as the ambulance is coming.

But, my dear, I can't without crossing that white line and... Oh, now, then make him pull over.

But you're not supposed to blow your horn in the city, my dear.

Just as you say, my dear.

I was driving about 50 yards behind their car.

Yeah?

They started to swing out of line and blew their horn, and then it happened.

This awful explosion.

I tell you, I've never in all my life... Where'd you get this note?

After the explosion, I noticed it lying in the front seat beside me.

Somebody must have thrown it in through the window.

What do you suppose it means, officer?

You know, Margo, there's something very peculiar about these bombings.

Mysterious explosions, I believe the paper here calls them.

There was another one last night.

You mean that freighter that blew up in the river?

Yes, Lamont, I was reading about it.

The paper says they found a note near to a nearby dock.
