A couple of simple Transit Drawings and a Café Drawing: the first two photographed; the latter scanned. What's nice about sleuth drawing is that they have to be fast and you don't have to show the subject, though often I do.
What I most like is that people aren't posing. They aren't presenting a persona to the artist; rather, they are engaged in what they are doing, whether it's reading, writing or unselfconsciously gazing into space thinking. They don't feel watched (as in a life drawing session) except in the ways we all watch each other journeying or working in public spaces.
I think these were all August 2015.
