Well. Have the Riften's court mage think of something to deactivate those devices and find out who planted them, if possible.

Amazing. He was so sneaky he managed to bypass Blades? Tell Delphine to train them harder. And how many times did he steal those table items?

By hearing dialogues found on http://uesp.net/wiki/Skyrim:Niranye#Conversations. Reading only first two dialogues is enough.
