Once you've got into that 'Boston Blackie' movie series, you just can't stop - they're so wonderfully funny, just plain 'murder entertainment' with vanishing corpses, car chases, and Blackie and the police (in particular Inspector Faraday) in turn working together and against each other to solve the most crazy murder mysteries. Probably that's EXACTLY what the audience wanted during the War: just plain entertainment to get away from the cruel reality for a short while...
This time, Blackie, trying to save a young lady's life, again becomes a murder suspect. The body (with the bullet in it that would prove Blackie's innocence) vanishes, the police chase Blackie, Blackie chases the corpse, the forgers chase the corpse AND Blackie - and finally the whole lot of them end up in a locked vault three stories below the ground and have no idea how to get out of there...
This hilarious adventure, just like all the 'Boston Blackie' movies, just NEVER gets dated - they're in black&white, you can tell from the clothes, the hairstyles, the cars that they were made in the forties... But are there any crime adventures today - complete with color, special effects and all - that are as entertaining as this great stuff that's more than 70 years old??
