Help with 57a please: Echo court imprisoning top inmate? Not any more (7)
I think the answer is escapee; Echo is E, and top inmate is also E, and the definition is inmate not any more, which seems to leave scape = court???
Yes, it's ESCAPEE.
The two Es are as you say. Top is CAP, surrounded by ("imprisoning") SEE. This is "court" in the sense of "to date someone" (eg, "They've been seeing each other for three months").
