New York is well known for being eclectic. When Stella Bonasera (Melina Kanakaredes) is invited by her friend Frankie (first seen in "Grand Murder at Central Station") to go to an "art scene", she is surprised that they go to see actual art.
One painting stands out. It is of a young woman with her face turned away from the painter. Looking at it reminded me of one of those magazine ads where a bunch of little photos make up a bigger picture. While Stella and Frankie are looking at the artwork, another couple is upstairs on the roof. The art scene turns into a death scene when their bodies are pierced by an arrow.
Mac Taylor (Gary Sinise) shows up and notes that whoever committed the double murder was good with a bow and arrow, since it only took one "killshot" to do the dirty deed. A later analysis of bloodstains found on the arrow's feathers shows that one droplet is from a jaguar, suggesting a hunter whose prey was human.
Across town, Danny Messer (Carmine Giovinazzo) and Lindsay Monroe (Anna Belknap) process the scene when a man is found dead outside a club. To complicate matters, a "mask" of glue covers his face. Danny notices that someone left glue splats behind and follows the trail to a darkened room where an all female band is practicing. Their manager is not happy to see Danny and demands to know what right Messer has to be there. Danny flashes his badge, and asks if the guy has noticed anything suspicious, like a man who is lying dead not far from the rehearsal hall.
Sure enough, the manager has glue on the bottom of one of his shoes. He tells Danny that he had thought the victim was simply sleeping off a drunken stupor.
