Definitely not. 'Wife of a Spy' is a made-up tale. It might incorporate some common themes or scenarios found in spy-related fiction, but it has no basis in actual facts.
Love and loyalty are also key themes. Despite the lies and danger, she may still love her husband and remain loyal. Or, her love could be tested to the point where she has to re - evaluate her loyalty. Additionally, the theme of identity could be present. The wife may have to hide her true identity or create a false one to protect herself and her husband.
I'm not entirely sure which specific 'Wife of a Spy True Story' you are referring to. There could be many stories about the wives of spies. Some wives might be aware of their spouses' activities and be involved in the espionage world themselves, while others could be completely in the dark.
I don't know for certain. It could be inspired by real events but could also be mostly fictional. Maybe check with the creators or read some reviews to get a better idea.
Most probably not. 'Spy On' is likely a product of the creator's imagination. While it could incorporate common spy tropes or themes found in real life, it's not based on a specific, factual account.
