And there was a lot of DiD. A lot. Sadly I only have one illustration on-hand, but from "Mystery of the Maya", there's this sad end for the female protagonist:

I remember in "The Case of the Silk King" it was possible to be kidnapped (with an illustration) and kept captive for a long time, bound and gagged. And in "The Lost Ninja", you could be kidnapped (also with an illustration) and tied up and carried away to a slaver ship. Look up those books if you're interested.
