The Fourth Hostage Rescue Mission will appear after finding 240 Riddler Trophies. The answer to the Enigma Machine Question is Shadow
Once you enter the Riddle Chamber his one looks quite intimidating but it's fairly easy.
First use the Cryptographer on the terminal behind you this starts a countdown follow the path to your left and around to the next section.
Directly across from you on the wall is a Question mark use a batarang to hit that and get ready to move again. Follow the bath and climb up to the catwalk above you.
Wait for the rotating Blades to pass and run across here. Then use the Line Launcher to shoot across to the next room.
Now to your left you should see some generators and a crate. All you have to do is use the Electric Charge to pull the crate toward you then use a Remote Batarang to hit the question mark. Easy enough.
Now enter the next room use the Line Launcher once again but get ready to change direction to your right about halfway across.
Zoom toward the Hostage, grab him and crash through the window and "BAM!" 4th Hostage rescued.

You will be able to rescue this hostage once you solve 240 riddles. See Genius for the Riddler Challenges guide. Go to the map location that appears after solving the Enigma Machine, break the question mark wall and enter.
Enter the first door and use the cryptographic sequencer on the switch behind you. It will shut off a path of floor panels. Cross them while avoiding the rotating spikes (duck under the poles that don’t have spikes on them) and reaching a grey platform. Look to your right and throw a batarang to a question mark switch, which will shut off another set of panels. Cross these and climb up the wall they lead to. Cross the conveyer belt, and at the end, use the line launcher to reach the back-left part of the room
You will need to detonate a weak wall to your left, and use the remote electrical charge to bring the box toward you. This will open the path for a batarang to hit a switch ahead of you. After this, you can use the line launcher to cross, and again in midair, similar to the last puzzle. Batman will grab the hanging hostage automatically if you did it correctly.
The hostage will give you new codes for your cryptographic sequencer. Use them, and solve 320 riddles for the next hostage (Brainteaser).
