A offbeat film noir from 1949 starring Glenn Ford & Nina Foch. Ford is a treasury agent hot on the heels of gathering information to convict a criminal through unorthodox means (he's building a case for tax evasion). Using dogged tactics to track down the bookmakers who keep the convicts' tabs (& confiscating their ledgers in the process), Ford's men, which include James Whitmore (in his screen debut), are a tight, professional lot but when the main con gets wind of Ford's activities, the usual goons are sent out to put pressure on the powers that be to lay off (even threatening Ford's wife, Foch, in the process). If only Ford can find one guy to testify & finally get the ball rolling in the right direction which proves easier said than done. That becomes the driving force of this story as Ford's tenacity is taken to the breaking point as his search becomes more desperate & dire. Running under 90 minutes, this film plays like an offshoot of the Charles Martin Smith character from The Untouchables (the books guy who figures out Capone can be got for fixing his books) which even though there aren't any gunfights to speak of, the tension is palpable & distinct. Co-starring Leo Penn (father of Sean, Michael & Chris) in a small role.
