Monk doesn't usually deal with purely domestic cases, but when an attractive woman comes to him in desperation after her successful businessman husband disappears, he has two reasons for taking on her case. First, he is short of funds. Second, he is intrigued with why her husband would, for the umpteenth time, try to rescue his twin brother, who lives from hand to mouth in the most dangerous part of London. He often returns from these visits upset, injured, his clothing in ruins, refusing to tell her what's happened. Monk's search is complicated by a typhoid epidemic and a subplot, not resolved, in which his memory loss trulythreatens him. The usual trial scene is as dramatic as always, but the resolution of the story isn't as satisfactory as most in the series. Still well worth reading.
