Theatrical Skullduggery . Penelope Fitzgerald is at her most devilishly entrancing in this tale revolving around the London acting school run (and I mean RUN!) by Freddie, a larger-than-life Gorgon whose will cannot be resisted. Fitzgerald has fun skewering the backstage pretentions, intrigue and petty jealousies of the London theater world of the early 1960s, but, clearly loving every seedy corner of it, she celebrates it with such gusto that you want to sign up on the spot for a season or two. That combination of wryness and fondness makes this short novel among Fitzgerald's most satisfying. And when Freddie goes out looking for a pound or two, hang on to your wallets

Ex Output:
POS

Sheer brilliance . I've seen a few reviews here that say "read it, but don't go see it." Most of the time, I would probably agree, because most people who do the play don't get it; they think it's a straightforward comedy, and it is almost anything but.    R&G is all about pace; except for a couple of spots, if the pace isn't almost franticly precise, the end loses its entire effect. The beginning of the second act    "Hmmm?"  "Yes?"  "What?"  "I thought you..."  "No."  "Ahh."    takes a lot of work to get right; someone missing a beat is almost as bad as someone walking through the invisible fourth wall.    Guildenstern has the first real line in the play: "There's an art to the building up of suspense." If you aren't on the edge of your seat when the penultimate scene begins, then the director and the actors have missed the boat.    Unfortunately, nothing Mr Stoppard has done since is quite as good. His plays are good, especially if you like the Pinteresque types, but just not quite as good

EXCELLENT READ - SOME OF THE BEST IN THIS GENRA . It has been some years since this one hit the shelves, but it is non the worse for wear.  Actually, I have to agree with another reviewer in that I too, feel this is one of Wambaugh's best.  A true sory, brought to light in a very readable story like format.  It is rather unforgetable.  The author does a very good job of not only telling us a story (Wambaugh is, after all, first and formost a great story teller), but gives us great insight into the thoughts and motivations of the killers.  He gives us a wonderful profile of the oung officer who survived this horrible crime.  I cannot in all truth say it is as good as "In Cold Blood," but it comes pretty close to the mark.  Recommend this one highly.
