The freshman comedy “Perfect Harmony” and the freshman drama “Lincoln Rhyme: Hunt for the Bone Collector” have both been canceled at NBCVariety has learned from sources.

“Perfect Harmony” wrapped its one and only season in January, while “Lincoln Rhyme” ended in March.

NBC declined to comment.

The cancellations come as networks and studios are grappling with how to proceed with the fall season in the wake of the production shutdown caused by the coronavirus pandemic. NBC had already renewed a number of its current shows prior to the shutdown, including “This Is Us,” “New Amsterdam,” all three “Chicago” shows, and “Law & Order: SVU.”

After disappearing for three years, the killer is back and Rhyme must team with young officer Amelia Sachs to catch him once and for all.
