I've been reading Gardner's Perry Mason books off and on for many years. Those who are used to really fine mystery writers may find Gardner's writing style a bit stiff and mechanical. Nonetheless, I still love the general setting: the characters of Perry, Della, Paul, Lt. Tragg, and Hamilton Berger. That, and the ingenious plots, are why I read Perry Mason.
On the whole, the ones written by 1950 are the best. This one was written in 1956, and is very good in some ways, less so in others. It is well written, a real page turner for most of its length. But the ending is too far-fetched.
It starts one unusually busy day at Mason's office. They need someone to type a long document. Della calls an agency. Soon a nervous young woman comes in to the office. Gertie assumes she is the agency typist and puts her to work. She notes that the woman, named Mae Wallis, seems anxious but is an extremely good typist. But after a few hours work the woman disappears, and the agency calls to say they haven't found any suitable typist!
It turns out that about the time Perry and Della were thinking of getting a special typist, the office of a South African diamond importer in the same building was being illegally entered by a young woman. She was seen and the police came quickly. It was Mae. She ducked into Perry's office to avoid the police. Hence the "terrified typist."
Soon Perry is heavily involved with the affairs of that South African diamond company. Two men run the LA office, Duane Jefferson and Walter Irving. An American named Munroe Baxter obtained diamonds from their European office and attempted to smuggle them into the LA area via an elaborate ruse. The scheme fell through and his accomplice, Yvonne Manco, informed the police. The police think he was murdered and arrest Duane Jefferson. Perry agrees to defend him.
The plot is quite complex and I won't attempt to summarize much more. The other partner, Walter Irving, is a classic arrogant Gardner character. His paramour Marline Chaumont seems to have an invalid brother she is very concerned about.
Very good Hamilton Burger. No Sgt. Holcomb, and only one brief mention of Lt. Tragg. The client is not especially sympathetic. In fact, he may be the least sympathetic defendant in any Perry Mason mystery. Average use of Della Street. Good use of Paul Drake. Mason is not in danger of being disbarred.
Recurring themes: not many. Shifting identities also occur in the Rolling Bones.
Unusual: the trial is the jury trial, not the preliminary hearing. The cross-examination scenes are good, even above average.
Very unusual: Perry loses the case! (Sort of)
The story is very good and held my interest very well until near the end. But the basic plot element is far-fetched. This is another Perry Mason story that couldn't happen today. Actually, I don't think it could have happened in 1956 either, but maybe. 1936, yes, that would be more believable.
Even assuming that the key plot element could happen, the story leaves too many questions unanswered at the end. For example, who gave Mae the keys to get into the office? Who was the second man in the boat, the one who rented it?
The cast:
Mae (Wallis) Jordan, terrified typist who finds a brief home in Perry Mason's office.
Duane Jefferson, one of the managers of the LA office of a South Africa diamond importing business.
Walter Irving, the other manager of the LA office of a South Africa diamond importing business.
Munroe Baxter, diamond smuggler who takes a dive.
Yvonne Manco, beautiful wife of Munroe Baxter and accomplice in a smuggling scheme.
Jack Gilly, witness to a strange scene in a small boat. Was it murder?
Marline Chaumont, friend of Walter Irving's in Paris and now LA.
Marline Chaumont's brother, a mental case and invalid, lives with Marline.
Ann Riddle, owner of the cigar store in Perry's office building.
Nan Ormsby, apparently the paramour of Duane Jefferson. She has no speaking part.
James Kincaid, alias of Duane Jefferson. Or is it the other way around.
Recommended for the unique ending. Very unique.
