Lloyd 'Michael Shayne' Nolan is hired by Ethel Griffies to retrieve a valuable coin for her, the Brasher Doubloon, which she is convinced was stolen by chorus girl Doris Merrick, who is also involved with her son James Seay. What starts out as a routine assignment quickly becomes a puzzle for Nolan as he finds the coin, but then Griffies informs him she also found it back in her personal belongings! Something is not right, and it includes murder, blackmail, Griffies' fidgety secretary Heather Angel and a seemingly inconspicuous photo taken years earlier...
Even tho this is a Michael Shayne movie, it's the first screen adaptation of Raymond Chandler's novel 'The High Window', which would be remade a few years later as 'The Brasher Doubloon' starring George Montgomery as Philip Marlowe. The plot is a maze, twisting and turning non-stop in its 60-minute runtime, as the always wise-cracking Nolan ('Lady In The Lake') goes from one clue/red herring to the next. You really need to pay attention or you'll miss things. This was the last of the Shayne movies starring Nolan and it does feel a bit rushed and less fun compared to the other ones. Having said that, it's still got its moments, and Nolan is always a blast as Shayne. But part of what made Nolan's Shayne movies so much fun was the continuous back&forth witty banter between him and the leading ladies (Mary Beth Hughes, Lynn Bari, Marjorie Weaver)... And this movie really lacks it as Angel's ('Lifeboat') character is nothing of the sort, and tough cookie Merrick ('Sensation Hunters') doesn't have quite enough screen time.
Director Herbert Leeds had already directed a few Shayne movies like 'The Man Who Wouldn't Die' so he knew how to direct these quick 'blink or you'll miss a clue' mysteries. DoP Charles G. Clarke ('Moontide', 'Violent Saturday') does a decent if unremarkable job. As mentioned, the movie does feel rushed, and while the crew obviously knew how to get the job done in a timely manner, it also shows. Not the best way for Nolan's Shayne to end, it's a slightly disappointing movie due to the high expectations created by the previous Shayne movies plus using a Chandler novel. A few years later Hugh Beaumont would take over as Michael Shayne for a new series of movies (which I've yet to see). Still good enough to watch for people interested in either Michael Shayne or Raymond Chandler.
