Query: Superb !!!

The two-year wait was worth it: this book is almost relentlessly perfect.Ms. George always chooses complex themes and in this novel she focuses on the aloneness of self and the essential unknowability of others. "In Pursuit" roams deeply and widely through the effects of this aloneness/unknowingness on our lives, loves, relationships, and - of course - our deaths.George has created interesting new characters, as she always does, to support her theme, but the familiar ones are present too, though slightly less knowable than usual. Again, a deft touch on the part of Elizabeth George.If there were a ten-star catagory "In Pursuit of the Proper Sinner" would definitely carry the banner.
