Real life jockey Billy Pearson plays a jockey here. He was also in the unsold pilot "Cool & Lam", based on Earle Stanley Gardner's series of novels published under the pen name "A.A. Fair". Both CBS Productions and Paisano Productions, which produced "Perry Mason" and the pilot, were to produce the proposed series.
Horse racing scenes were shot at Santa Anita racetrack just outside Los Angeles. A favorite of celebrities and local gamblers, it first opened on Christmas Day 1934.
One of the few episodes with a scene looking into Perry's office from the balcony area. After Perry first confronts Tic Barton's wife, there is a scene where Perry, Paul and Della discuss some early findings in Paul's investigation. Everything in the office is reversed from usual camera angles in the series. Perry's desk is on the right, not the left; the door to the back hallway is on the right in the background, not on the left in the foreground; and we see the wall behind that door, which is usually never seen because of the camera angle.
Some of the music cues in this outing would later be used in The Twilight Zone (1959). Also, one of the first times in season two where a jazz noir music soundtrack is used.
At the horse stables, jockey Francis 'Tic' Barton (Billy Pearson) talks to horse trainer Eddie Davis (Joe di Reda), who gives Tic a phone number to call his wife. The phone number is Webster 1-2499, the same phone number painted on the side of the Walsh Appliance Company delivery truck seen at the start of the preceding episode.
