Danger by My Side (1962)

When her undercover police officer brother is killed in an hit-and-run, "Lynne" (a competent Maureen Connell) is convinced that the job he was on is the cause and so sets about an investigation, in cahoots with "Insp. Willoughby" (Anthony Oliver) of her own. Quickly, she is embroiled with nightclub owner "Venning" (Alan Tilvern) discovering that he presides over a gang of petty thieves - but nothing to connect him with her brother. Until, that is - well it all centres around trips to Europe and diamonds. There's nothing particularly original here, but the absence of a star leaves for a consistency of rep-style performances that keeps the story fairly taut and watchable. I didn't love the conclusion - all a bit rushed, but as these hour long afternoon filler-features go, this is quickly paced and competently presented. Nope, you'll never remember it, but it's worth watch.
