If you are a member of the radio generation, this series represents the VERY BEST of that generation. I read all of the Nero Wolfe series, and as a child I listened to Sydney Greenstreet. Once again, I was transported through that aesthetic distance to the never-never land of the imagination.
If you are not a member of the radio generation, try it. You might be shocked. You may find Greenstreet's renderings strange and/or wonderful. Who knows?
