Austin James (Parker Stevenson) is a reclusive genius and President of Serendip, a high-tech consulting firm he founded. However, he's too irritated by average people to come up with solutions for them and instead conducts random experiments in his warehouse full of devices (most of which he appears to have designed on his own) For Science!
Michelle Castle (Ashley Crow), also known as Mickey, is his Beleaguered Assistant. Serendip hired her to be Austin's secretary and uses her to get Austin involved in things outside of his warehouse, like his job. Conventionally intelligent, she's the latest in a line of secretaries sent to Austin by the CEO of Serendip.
Together, these two encounter out-of-control experiments, supernatural events, and mysterious deaths. As you might expect, Probe features heavy doses of scientific knowledge and logical reasoning, but was cut short due to the 1988 writer's strike.
Probe provides examples of the following tropes:
- '80s Hair: Austin's designer mullet and Mickey's post-dryer frizz with bangs are classic examples of the contemporary styles for men and women of the 1980s.
- Affectionate Nickname:
- Austin calls Michelle Castle "Mickey".
- Michelle (in private) calls Austin James "Jimmy".
- Amateur Sleuth: Austin James is constantly trying to learn what he doesn't already know. This includes discovering how various people are murdered. The first episode establishes him to have a good working relationship with the police coroner, but his actual job is President of Serendip (which he hates and actively avoids so he can do scientific experiments instead). Michelle Castle is hired to be his secretary and she helps him solve each episode's mystery.
- Always Murder: While Austin is fascinated with a diverse array of interesting topics, the plot of the episode always revolves around at least one murder. Because the pilot episode is a two-parter, it has two murder mysteries to solve.
- Bluff the Impostor:
- "Black Cats Don't Walk Under Ladders (Do They?)": During The Summation, Austin uses the killer's own knowledge against them, causing them to believe that they've been affected by the same poisoned tea that was used to kill Marty Corrigan. He has to do it because until the killer confessed, he wasn't sure which of the suspects had done it.
- "Now You See It....": At the climax of the episode, Austin James has recreated the murder method that was used to kill the previous two businessmen. He confronts his prime suspect with the situation (which includes an empty elevator shaft covered by a Hologram) and tricks him into confessing. The murderer does, but then tosses Austin down the empty shaft. Serendip's CEO and several police come out from around corners to arrest him. (Austin is fine, having anticipated this, lying safely on a crash cushion.)
- "Plan 10 from Outer Space": Because he didn't have any evidence to determine if Trish or Helga committed the murder, Austin has to trick the murderer into confessing, by using the victim's sunglasses, which he says created a photonegative when the victim was electrified. When the murderer sees herself on the wall, she immediately starts trying to defend herself.
- Beleaguered Assistant: Mickey is hired at Serendip to be Austin's assistant. He really doesn't want one, and tries to chase her off like he's done to the previous secretaries sent to him by the CEO. Note that Austin is founder and President of the company; Mickey finds herself in the unenviable position where if she doesn't make Austin happy, he will fire her, and if she doesn't make Austin do at least some work for the company, the CEO will fire her. She slowly grows out of this role, becoming more confident in her ability to get productivity from Austin and keep him engaged in interesting experiments.
- Bunny-Ears Lawyer: Austin is a genius, holding enough patents and royalties from his inventions that he founded Serendip without any investment help. He's also socially awkward, callous, and, by self-admission, mildly schizophrenic. It becomes Mickey's job to manage Austin's quirks so that he remains a net benefit to his own company.
- Dainty Little Ballet Dancers: One of Michelle's childhood photos shown in the Title Montage depicts her in ballet clothes, practicing. It's a feminine contrast to Austin's mechanical masculinity.
- Eureka Moment:
- "Computer Logic": When Mickey tells Austin that the broken rose petal reminds her of a piece of glass, he finally makes the connection to what happened; this episode's death was caused by liquid nitrogen.
- "Computer Logic, Part 2": Michelle tells Austin to think about who can dial a phone, but doesn't like to talk, and knows all of Austin's unlisted telephone numbers. He immediately realizes that the mysterious figure who has been prank calling him and causing the mysterious electrical behaviour must be Crossover, the A.I..
- "Untouched by Human Hands": When Mickey points out that Austin can't be aware when every acorn falls, he thinks of tea. That chain of random thoughts helps him realize that there was something wrong with the tea in the radiation lab. The glass of tea in the video was full, but they sent the robot in when it was half-empty.
- "Metamorphic Anthropoidic Prototype Over You": While decoding Josephine's writings, Austin realizes that she thinks all of reality is just like on television. Her morality is based on things like Soap Operas, where killing romantic rivals is acceptable behaviour. He immediately calls Mickey and tells her to lock down the warehouse for her protection.
- "Plan 10 from Outer Space": Reading the letter from the lightning rod company helps Austin figure out what really happened to Truman. He tells Mickey to get the other two characters and he's going to show them who "Rexel 14" and the murderer really are.
- First-Name Basis: Before the end of the first episode, Austin and Michelle are familiar enough with each other that they use first names and nicknames.
- For Science!: Austin is often more interested in the pursuit of scientific research instead of whatever other demands on his time are being made, demands like running his company, socializing, or paying bills.
- The Gadfly: Austin's intelligence and self-diagnosed schizophrenia cause him problems when it comes to relating with other people. Because of this, he intentionally provokes responses from people with a disrespectful attitude to amuse himself and get answers to his questions. People in the scientific field tend to admire him, while his business contacts tend to hate him.Michelle Castle: Why do you enjoy tormenting people so much?
Austin James: Because when I torment them, I get what I need. Answers! It's nothing personal.
- Girl Friday: Michelle Castle was hired by Serendip to be Austin's secretary. She manages his appointments, provides a different point of view (often leading to a Eureka Moment), and things Austin can't begin to describe.
- Insufferable Genius: Austin James, from this short-lived '80s sci-fi mystery show, is the smartest man on the planet. And he never lets you forget it. Ever.
- Intelligence = Isolation: Austin hates being around other people, finding them to be irritants and distractions from his pursuit of more knowledge. Except Mickey, whom he respects despite not being as knowledgeable.
- Mirrored Confrontation Shot: At the end of the Title Montage, Austin and Michelle are looking at each other across a table while a glass (half-full or half-empty?) with water sits between them.
- Mother Nature, Father Science: Michelle is a secretary whose scientific education is rather low, and would insist on some answers only being felt, rather than relying on the scientific method of recording and replication. Her Foil is Austin James, a genius who gets excited when he doesn't know the answer and believes that observation and replication will provide the answer to all of life's mysteries.
- Multi-Part Episode: The first episode is titled "Computer Logic", while the second episode (initially airing immediately after the first) is titled "Computer Logic Part 2". In order to have a murder solved in each episode, the first part has a subplot about a woman who supposedly died of exposure solved by Austin before the end of the first hour.
- Omnidisciplinary Scientist: Austin is familiar with a wide variety of scientific fields of study. He demonstrates computer programming skills several times, is interested in neurological uplift programs, and tries to solve mysteries in his spare time.
- One-Word Title
- Once per Episode: Every episode, Austin will solve a murder mystery.
- Photographic Memory: Austin claims to have the ability to recall everything perfectly, an aspect of his high intelligence. Mickey is pissed when she finds out because he's been having her write down everything that's been said (for no purpose, since he remembers it perfectly). When it's brought up again later, he claims to have been certified by the government for having a recall that is five times more effective than the best computerized directory.
- Robot Me: The Title Montage includes a picture of a young Austin between two blocky robots with flexitubes for arms that are made to resemble a man and woman. It's signed with love from his parents. Michelle finds this photo in the Premiere while Austin is taking a nap.
- Romanticism Versus Enlightenment: Austin James gets aggressive when he hears people around him repeating pseudo-scientific claims and trans-dimensional mumbo-jumbo. Unfortunately for him, his secretary Michelle Castle has almost no understanding of current scientific models or the scientific process. They conflict over this issue several times during the Premiere, but have a much more settled relationship for subsequent episodes. Austin remains an Enlightenment supporter and Michelle is more into Romanticism.
- Sassy Secretary: Michelle has no problems talking back to her boss Austin (it helps that her initial contact was coloured by the fact that the Director who hired her said she wasn't to let Austin fire her, so she had to come up with a few creative excuses why he had to let her follow him). Midway through the series they're more respectful to one another, but the first episode has them yelling at each other fairly often.
- "Scooby-Doo" Hoax:
- "Black Cats Don't Walk Under Ladders (Do They?)": Austin, along with several other scientists, have been invited to be on the Show Within a Show, The Marty Corrigan Show while local witch, Sabrina Stillwater, tries to hex the host. They're supposed to be debunking her "magic", but when the host actually dies after she casts the hex, Austin and Mickey being to look for evidence to prove who really killed Corrigan.
- "Plan 10 from Outer Space": Austin has been called to a mansion in the desert of New Mexico. The mansion's owner, Truman, claims that an alien is trying to kill him. Unfortunately, Truman dies before Austin can prove him wrong (because someone else killed him). Austin has to explain who killed Truman and what Rexel 14 really is.
- Smart House: Austin has wired up his workshop/warehouse with the ability to respond to complex voice-activated commands, but not quite autonomous responsiveness. He uses it to answer the phone, play music, and do intensive research.
- Smart People Play Chess: One of Austin's childhood photos shown in the title sequence depicts him taking part in a chess competition against several much older players. At the same time.
- The Teaser: Each episode starts with a Montage of clips from later in the episode. They're selected from the most action-packed scenes for the episode, but the first part of the Premiere used completely unique footage, with a Dramatic Chase Opening to establish a mysterious person is able to Hack the Traffic Lights and indirectly kill people.
- Title Montage: Black-and-white photos from Austin's and Michelle's childhoods are presented in Montage form, interspersed with brief colour videos from the episodes. Halfway through the opening, the black-and-white photos change to be about the two of them as they are now. The opening ends with Austin and Michelle looking at each other across a table while a glass (half-full or half-empty?) with water sits between them.
- Too Good to Last: The pilot episode aired the same day as the start of the 1988 writer's strike. It managed to limp on for a few more weeks, but Probe was killed off, despite having Isaac Asimov's notoriety and fanbase to support it.
- The Watson: Mickey's primary role in the narrative is to ask questions from Austin and others so that the audience is aware of the clues.
