She hasn’t staked it out. It’s not familiar terrain. You can’t just dump a body in a canal and hope that works. You need to know tides/ water flow. Does it need to be weighted. The depth of the water. Serial killing takes work to not be caught. Have you not seen Dexter? There is planning involved. We know she had time to think about the Thames. So avoid that area and you should be golden. Also if you run into trouble in Amsterdam just tell them “damn you gonna risk mugging a serial killer, bold move.” 🤪
