I really enjoyed this, but the petty reason to not give 5 starts is that my editing brain reared up again. You can't have someone take off their tie, jacket and shirt, and then 5 pages later have them take it off again, when they were busy with other stuff in between that was not 'putting their clothes back on'. (and some of those 'word sounds the same but has different meaning in this spelling' cases, or just a typo making a different word. Didn't notice the same in parts one and three of the series, wonder if this one was more rushed maybe.)
