I don't really know. You'd have to look into the background and the creators' statements to get a clear idea. But often, these things are not straightforward and can be open to interpretation.
Signal is not based on a true story. It's a creation of the writers' imagination, although it might draw inspiration from various real-life elements to add depth and relatability.
It's not based on a true story. The Signal is a work of fiction that takes viewers into an invented world with fictional characters and events to tell an engaging tale.
The moral of 'The Signal-Man' could be about the power of the supernatural or the psychological impact of fear. The signal man is haunted by apparitions which lead to his doom. It shows that we should not let our minds be consumed by unexplained and terrifying things, as it can cloud our judgment and lead to bad outcomes.
I'm not sure specifically as there could be many 'the signal' short stories. It might be about a mysterious signal received from outer space, perhaps dealing with the discovery and the attempts to decode it, and the implications it has on the characters in the story.
The true story influenced the overall mystery - solving aspect of the plot. Since it was based on real cold cases, the drama had a sense of authenticity in how the detectives went about their investigations. For example, they had to dig through old files, re - interview witnesses, and face the challenges of evidence that had been lost or corrupted over time.
Another possibility is that there are multiple main characters in the story. For example, a group of astronauts might be the main characters if the signal is received while they are on a space mission. They would have to decide together how to respond to the signal, and their different personalities and backgrounds could create conflicts and cooperation within the group as they deal with this unexpected signal.
I'm not sure specifically as I haven't read it in detail. But generally, a short story has a central plot that could involve characters in a particular situation, facing challenges or going through some kind of emotional journey.
