It wasn't featured in Shadowrun Returns, but as it exists in the Shadowrun world and might help Zeloth too, I would like Fortuna to receive a slightly old laser microphone.

Description from the 2E rulebook is:
This device bounces a beam against a solid object, reading the vibrational variations of the surface and translating them into the sounds that are occurring on the other side of the surface.

I assume it comes with a headseat/ear pieces to listen without alerting anyone else they're being listened to.
