Comcast Center

Comcast Center, also known as the Comcast Tower, is a skyscraper in Center City, Philadelphia, Pennsylvania. The 58-story, 297-meter tower is the second-tallest building in Philadelphia and the state of Pennsylvania, as well as the twenty-third tallest building in the United States. Originally called One Pennsylvania Plaza when the building was first announced in 2001, the Comcast Center went through two redesigns before construction began in 2005 before opening in 2008. The building is named after its lead tenant, cable company Comcast, which makes the skyscraper its corporate headquarters.

The gang solves a huge mystery all while finding evidence at the Comcast Center with the help of a chess-playing wind-up doll named Lavinia Guilfoyle.
