The first of the three fifties movies featuring Peter Cheyney's character:Callaghan!!! .The IMDb rating is currently pretty low and I can find little fault in the opinions expressed.
"A Toi De Jouer " is the umpteenth story of an insurance swindle :a ship has sunk and it might be (must be more like) criminal .Callaghan is working for the insurance company and he investigates on dry land and on the sea (he swims a lot).
There's a little humor "you've read too many Cheyney's detective stories!" "we are not in a thriller.-We are ,in a certain way!".It makes up a little for the ponderous fights between the hero and a heavy played by Robert Berri.But just a little.
