It seems most difficult to marry comedy and crime. This is another example. Great cast, nice jokes, suspense.

The intense Nina Companeez, famous later for her "Dames de la cote", failed here. (She credited as primary dialogue writers) The depths that such an undertaking requires wasn't met, however.

Superficiality poses no problem in comedy. But it tends to kill crime. And here, despite of an amazing and promising story, diving into the criminal element wasn't done in sufficient depth. On the other hand, all possible comedial possibilities were exhausted. At times detrimental to the crime part.

Therefore we end up with yet another past-time worthwhile watching; and at the same time deploring the missed opportunities.

To name just one single example: When father commissionaire asks for the photo of Jo, his son says it is missing in the files. Father then gives him two minutes to get it, if not he'll direct traffic in Martinique (so to say). He then rams his head at the closed door, falls to the ground. In that moment an agent enters, Jo's photo in his hand, 'it was at the printers'. If this is what we wanted to see, we'd be watching Laurel and Hardy.
