Squishy Taylor and the vase that wasn't

Squishy and her twin "bonus" sisters Vee and Jessie are intrigued when a Ming vase disappears from the apartment above them, especially when they find out it is apparently one of a set stolen during the Opium Wars--and when they hack into the apartment building's security cameras and see what appears to be the ghost of a Chinese warrior they are determined to investigate the mystery.
