Sherlock goes missing.Joan takes matters into her own hands.

Sherlock and Joan investigate a series of break-ins at an up-and-coming art gallery, a tea shop owner is contracted to kill a reclusive artist. Joan thinks she's got this figured out, but she might have it all backwards.

Sherlock continues to push at Joan, intent on the idea that life with him will only cause her ruin; but when she finally finds someone who may be more than just a diversion, Sherlock finds himself dealing with jealousy beyond his control, and the realization that he may have pushed her once too far.
