There is not a ton of concerning content here, but we captured a few notes to point out:

• Before the book starts, we see an advertisement for future titles in this series. The third book in the series pictures a girl (we find to seemingly be a girlfriend of one of the Hardy boys) wearing a short skirt. This comes up in an illustration in this first book too, as she dreams of performing one day and is wearing something very similar. The advertisement for a later book shows a villain that is drawn to look pretty creepy.
• In an attempt to catch up with a runaway horse, one of the boys all of a sudden appears on a motorcycle. When his brother asks “How’d you learn to hotwire a motorcycle?” he responds, “The internet is a wonderous place”.
• The adventure brings the brothers to a “hacker’s ball” which we are told is like “a rave for hackers”. One of the brothers jumps to a computer and is able to quickly find the host’s real (embarrassing) name. This does all feel like it sends a bit of a mixed message on hacking.
• To create a much-needed distraction, one of the girlfriend characters slaps a totally innocent man, loudly implying that he had done something to deserve it. She stands by while the man is escorted out. To make it worse, when asked what he had done, the author has her answer, “Nothing. But I am sure he was thinking it”.
• One of the brothers jokingly says, “Is it me, or do I look hot?”
