This is Your FBI - Murder on the High Seas

It is 9:30 PM and the small American freighter, the Edna Mae, out of Maracaibo continues steadily on its northward course toward New Orleans. In his cabin under the bridge, Captain Peterson has been dinner host to two of the ship's passengers, a Dr. Mahler and his secretary, Miss Karen Brennan. Suddenly, Mr. Raimy opens the door and says "Beg your pardon, Captain. It looks like it is making up in the northwest. Captain says "Secure everything, I will be along". Raimy says "Right, sir". Captain says "Well, I'm afraid folks, it is going to get a little rough. The Doctor and Miss Brennan thank the Captain for the wonderful dinner, and start to make their way to their cabins. As they walk past the radio room, Miss Brennan says "Oh, wait a minute. I've left my handbag in the Captain's cabin". The Doctor says "I'll get it for you my dear. You go on ahead to your cabin". Miss Brennan says "Thank you Doctor. Be careful because it is getting rough out here". As he heads back toward the Captain's cabin, he has a deadly encounter someone unknown to him.
