Cary Grant is on excellent form in this ultra-sophisticated crime caper. Having long since retired to life on the Côte D'Azur, "John Robie" finds himself at the centre of enquiries as his "Cat" appears to have resurrected itself and is robbing rich folks of their jewels. John Williams again steals his scenes - this times as the insurance adjuster "Hughson" who is convinced, enough, by Grant's protestations to agree to work with him to find the true culprit. Enter the wealthy Jessie Royce Landis ("Jessie"), a self-made American millionairess and her glamorous daughter "Frances" (Grace Kelly). The mother is determined to find a match for her girl - and well, the romantic roots are well and truly planted. Hitchcock keeps us guessing for quite a while as the romantic and criminal threads develop in parallel before tying together in quite an exciting climax. At times I have found Kelly to be just a touch too aloof, but here she still has enough of a foot on the ground to play her part well providing for an engagingly mischievous chemistry between the two of them.. The attention to detail is super, too - and it's easy to become subsumed in the lazy, rather vacuous, but very enviable lifestyle of the rich and famous!
