Living in a private home used to be quite a risky affair. This was particularly true in our country during the late 1990s. The crime rate was sky-high, to the extent that people were genuinely terrified of spending the night alone at home. As a result, almost every family residing in a private home owned a dog for protection.
Thankfully, those days are long gone. The advent of high technology, the widespread installation of video surveillance cameras, and an overall decline in the crime rate have collectively led to a significant decrease in thefts and robberies.
Now, let’s turn our attention to today’s puzzle. We’ll reveal a partial answer to it at the end of this article.
Take a good look at this young man. Here’s the situation: at 4 a.m. local time, before the sun even started to peek over the eastern horizon, he heard a strange noise coming from inside his house. If he hadn’t been living alone, it might not have been such a big deal. But he didn’t have a dog, a cat, or even any fish in an aquarium. That’s precisely why he reacted so strongly to the noise.
Examine the details more closely. The clues aren’t really hidden all that well, after all.
