The film is a spin-off from a popular BBC radio series of the 1930s, Inspector Hornleigh Investigates,^[2] created and written by Hans Wolfgang Priwin, which ran on the BBC from 1937 to 1940.

The screenplay was not written by Priwin and the leading characters are somewhat modified. The actor who played Inspector Hornleigh on the BBC, S.J. Warmington, is replaced by comedian Gordon Harker, and is given a bumbling sidekick, played by Alastair Sim, solely as comic relief. The BBC series was a serious detective drama, but in the film the two leading characters play the script for laughs, and the casting of two well-known comedy stars in the parts indicates that this was the director's intention. The rest of the cast behave as if they are in a straight drama, highlighting the behaviour of Harker and Sim.

To emphasise that this was a comedy film series, and to enhance the comedy double-act between Harker and Sim, the subsequent films in the series were written by the comedy writers Frank Launder and Sidney Gilliat.

The film was made by Twentieth Century Productions Ltd in October-November 1938^[3] and released in April 1939.

The film was sufficiently well-received by audiences to justify two sequels: Inspector Hornleigh on Holiday (1939), and Inspector Hornleigh Goes To It (1940).

• The New York Times called the film "a neat bit of British detective fictionizing, as tailor-made as a Bond Street jacket, now on view at the Rialto".^[4]
• TV Guide wrote, "though the film is well-plotted and well-acted (Sim is hilarious), the thick English and Scottish accents were often incomprehensible to American audiences. Aside from that, the suspense is nicely built towards a good denouement".^[5]
• Vintage 45 wrote, "this works as a mystery and the occasional snide remarks between Hornleigh and Bingham work to lighten things up a bit. The movie is fun and clever".^[6]
