While Veronica went shopping with Krista and Ms. Arian. Michael kept watch on the Riggs Residence. He was there before the sun even rose, so he wouldn't miss any unusual movements.
He observed mansion staff moving in and out. Late morning, Ed Riggs left the residence in one of his private carriages.
Michael used his own hired, nameless carriage to follow him. The route he took was strange and convoluted. It was full of loops and they went over the Flumen Libertatis multiple times, back and forth.
Obviously, he wanted to get rid of any unwanted attention. Michael's carriage driver kept a suitable distance from Ed's carriage, so they never noticed him.
After circling for an hour, Ed's carriage eventually stopped and parked in front of a famous cafe. Michael watched and waited, but nobody got off the carriage.
