This picture of the bottom floor is meant to entice people. See? It's an interesting place. It has drugs! It has the Curve restaurant, and the Cloister Inn.

The Cloister was a nightclub with a good rep. From Chicago Crime Scenes:

 There were typically three nighly shows, at 10 p.m., midnight, and 2 a.m. With jazz legend Ramsey Lewis leading the house band, popular acts that played the Cloister included Duke Ellington, Anita O'Day, Damita Jo, Buddy Rich, Art Blakey, Sally Rand, Redd Foxx, and Bill Cosby. Lenny Bruce had his first Chicago engagement there before moving on to the Gate of Horn club around the corner on State and Oak streets, where he was arrested and assaulted by police. Some period ads from the 1950s, enticing clubgoers with major acts including George Carlin, Della Reese, and Jim Backus

You'll have to go to the page to see what the crime was.

That'll do for now - more down the road, some time.
