I've been reading Gardner's Perry Mason books off and on for a long time. 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 Burger. That, and the ingenious plots, are why I read Perry Mason.
On the whole, the ones written by around 1953 are the best. This one was written in 1964, in the latter part of the long run of the TV series. It is good and very clever. The writing is not so dry and repetitious as is often the case in the late books.
Wealthy businessman Horace Warren comes to see Perry Mason with an odd story. He thinks that someone is blackmailing his wife, and he has a fingerprint of the suspected person. He wants Perry to find out who it is, and to protect his wife from that person at all costs. Furthermore, he thinks the person is an acquaintance who will be at a party he is giving that night. He wants Perry to come with a feminine partner. He sends his right-hand-man, Judson Olney, to come see to Perry to hatch a reasonable story to explain Mason's presence. Olney makes up the tale that he once met Della Street on a cruise, ran into her recently by chance, and so invited her and a date.
To solve the fingerprint question, Mason hires Paul Drake to get a catering service that fronts for a group of fingerprint technicians. They will gather up the used plates and glasses and lift fingerprints of the guests. Fortunately there is in LA a dummy catering truck that is really a fingerprint lab(!) What?? How likely is that in real life?
Real or not, that's the setup. Perry and Della attend the party and meet various acquaintances of Warren. Paul Drake does indeed find out who made the fingerprint Warren had. I won't reveal the name here.
Who would be blackmailing Warren's wife, Lorna? Turns out that years earlier she had been arrested and tried for a crime in New York. She was acquitted, but a man she worked with named Collister Gideon was also tried, and he was convicted. Gideon has just been released from prison. Is Gideon the blackmailer? Before long Warren meets him in a deserted warehouse where Gideon is murdered. Warren is arrested for the murder.
There are several interesting plot twists, including a suitcase containing $47000 (the "phantom fortune") and a clever plot by Perry to put pressure on the blackmailer.
Good Lt. Tragg, very good Hamilton Burger. Good use of Della, good use of Paul Drake. Mason doesn't play any clever tricks to confuse guns or switch fingerprints, but he does hatch a clever plan to thwart a blackmailer. Hamilton Burger thinks it was too clever. He's determined to get Perry disbarred this time for sure!
There aren't really too many suspects. The cross-examinations are very good. I had no trouble guessing the culprit.
Unlike many of the later Mason stories, this one does not seem to be too unlikely to actually happen to real people. However, it is marred by some coincidences. I can't go into details without revealing spoilers.
Some of the later Mason stories introduce characters very late in the book, well past the 50% point. This one is the opposite. Several of the characters listed here appear early in the book but are never mentioned again after the 40% point. Also, the original impetus, the fingerprint Warren brings to Perry at the start, is never explained.
I can't recommend it. If you love seeing Hamilton Burger get defeated, you'll love this one.
