Private Eyes (1953)

A hit on the nose by Herbie gives Sach mind-reading power, prompting Slip, Chuck, Butch and Louie to buy the Eagle Eye Detective Agency... using, of course, Louie's money. In waltzes Myra Hagen, who leaves the boys a valuable fur coat and a sealed letter to be given to the District Attorney in the event anything happens to her. John Graham, posing as an insurance man, makes his entrance following Myra's exit, but he's actually connected with fur crooks. He is given the coat but the boys are unable to produce the letter, which vanished after Sach blew up their safe and wrecked the office. In the event it shows up, Professor Damon, leader of the gang and operating a Health Farm as a cover, has henchmen Soapy and Al kidnap Herbie as a ransom against the delivery of the letter, which blows the lid on the gang. Slip, disguised as a Viennese doctor, and Sach, as an invalid old woman wearing Mary Pickford curls, visit the Farm to rescue Myra and Herbie.
