I've worked my way recently through about 10 of the films in the Chan series and this is one of the most compelling I've seen yet -- largely due to the good chemistry between Warner Oland and Henrietta Crosman, who is one of the more memorable of the leading ladies in the series. True, the Chan family is missing -- except when viewed briefly in a photograph at the film's very end -- and the San Francisco location isn't very convincing; it is hard to place the "ancient" house where much of the action takes place in a city where most everything was burnt to the ground in 1906. Nevertheless many of the typically alluring elements of the Chan films are present in full force -- society ladies in long dresses, a shady pair of mediums, séances that come to a screaming end, pitch black scenes in secret rooms, and odd applications of 1930s technology. Jonathan Hale is a welcome presence and the comic relief supplied by Herbert Mundin as the butler stops short of being annoying, which is more than one can say for some of the later entries in the series. All in all quite satisfying.

Warner Oland is Charlie Chan in "Charlie Chan's Secret" from 1936.

Charlie is attempting to ascertain whether a man named Allen Colby is dead or alive. After seven years of being away, he's announced to his family that he is on his way home to claim the family fortune. However, the ship that he is on sinks near Honolulu, and he is presumed drowned. But is he? Charlie sees in the journal Colby left behind that there have been attempts on his life. He heads for the family mansion.

There he sees the matriarch of the family (Henrietta Crosman) and other family members. Henrietta is involved with a psychic and has séances at her home to connect with her late husband. During one séance, the body of Allen appears - dead. It's the actual body -- he arrived home, was murdered, and then hidden until the séance. Charlie has to find the killer.

It's not hard to figure out the killer, but that doesn't make the film any less entertaining. Warner Oland was a delightful Chan, cheerful and funny, with more energy than the older Sidney Toler. The rest of the acting, with the exception of Crosman, isn't very good - in fact, it's bad -- but Oland keeps it going.

Some nice spooky elements, some sinister-looking people, and a fun mystery.

Missing for seven years, Allen Colby, heir to his father's fortune is no longer welcome at the Colby/Lowell home. His arrival would mean that the supply of funds doled out by his father's estate under matriarch Henrietta Lowell, Bernard Colby's sister, would come to an abrupt halt. Henrietta has an abiding interest in all things psychic, and has spent nearly one hundred thousand dollars on psychic research, séances, and payments to Professor Bowen and wife Carlotta to stay in touch with the dead.

Although it's presumed Allen Colby drowned when a cruise ship went down, detective Charlie Chan (Warner Oland) has his doubts. With no body, and a recovered briefcase bearing the initials "A.C.", Chan believes the missing heir will show up. Indeed he does, but not as expected. Gaining entrance to the old Colby homestead, Allen is quickly dispatched by a knife in the back thrown from a parlor trapdoor. His corpse does make an appearance though, at a scheduled séance meant to determine his fate. With Colby truly gone, the remaining Colby/Lowell heirs can gain some measure of satisfaction - or can they?

The film does a nice job of presenting a number of possible suspects to the Colby murder. Attorney Warren Phelps, the administrator of the Colby fortune stands to lose a substantial portion of his income from fees paid for his services. Henrietta Lowell would lose all of her psychic research funding, and her two daughters would be cut off as well. Accordingly, Professor Bowen and wife Carlotta would no longer enjoy their séance income if Allen Colby showed up to claim his inheritance. And for good measure, the film offers caretaker Ulrich as a suspect; his daughter was in love with Colby years ago, but died some time after Colby disappeared seven years earlier.

Charlie Chan approaches the case methodically, and begins to unravel the case a step at a time. When he demonstrates to Mrs. Lowell how the séances were rigged by the Bowen's, she becomes a loyal ally to uncover the mystery, to the point of faking her own death when the killer lashes out. But with all the meticulous work done in laying out the suspects, the identity of the real murderer still comes as a surprise at the end. In typical Chan fashion, the killer had a stake in Colby's disappearance, but there were no real clues to implicate him throughout the film.

With no Chan family members on board for this film, the comic relief is handled by Lowell butler Baxter, nervously but effectively portrayed by Herbert Mundin. As if to lend further credibility to mysterious psychic forces at work in the Colby House, a black cat named Lucifer snarls his way into a couple of well placed scenes. Sufficiently dark and moody, "Charlie Chan's Secret" is a well told mystery that nicely complements other films in the Chan series.
