Select the correct sentiment of the following review: Along with Patrick McGoohan and Robert Culp, Jack Cassidy was an iconic Columbo villain. The very first "proper" episode of Columbo, following two standalone pilots, "Murder By The Book" is not far off classic status.

Jack Cassidy plays Ken Franklin, one half of a murder mystery writing partnership. His partner Jim is the talented one, whereas Ken has no talent other than the gift of the gab and a skill for promoting the books. As soon as Jim has decided he no longer requires Ken's marketing skills, Ken hatches a plot to kill Jim. Except it's not a new plot, it's actually the implementation in real life of a murder storyline originally intended for one of their books.

It doesn't take Columbo long to work out that Ken is the murderer, although unfortunately another murder has to take place (Ken romances and then kills a key witness) before Columbo has enough evidence to secure a conviction.

Nothing whatsoever wrong with "Murder By The Book", but it's not quite top-notch. I would just give "Publish Or Perish" the edge over this: both episodes feature Jack Cassidy and the world of publishing, but "Publish Or Perish" is a fraction more tense and unpredictable. But this is still a great episode.
