One Man's Treasure

When a man's body is stuffed into a garbage chute in an apartment building, Castle and Beckett are forced to untangle a twisted web of dual identities, one married, one engaged, and an underlying tale of cutthroat corporate competition that wound up with two very offended women, a dead body, and a lot of confusing facts. Meanwhile, Alexis's school encourages her to do volunteer work, which she arranges to do at Beckett's precinct.
