In this entry in the enduring series, the suave jewel thief finds himself helping the police break up a ring of diamond smugglers. Along the way, he winds up accused of both robbery and murder.
Determined to actually take his fortnight's leave this year, "Jamison" (Eric Blore) stages what amounts to a mini-revolt against his boss "Lanyard" (Gerald Mohr) - even refusing to do up his bow tie for him. The compromise - well they are both going to Mexico. Of course, trouble is never far away and when a croupier is killed, suspicion falls on the "Lone Wolf". Meantime, they also encounter the outwardly wealthy "Agatha Van Weir" (Winifred Harris) who is $50,000 in the hole to the crooked casino owner "Henderson" (John Gallaudet) and who has been using her diamond as collateral. Clever people might realise that being around "Lanyard" is just too risky - and when the wife of a diamond dealer (Sheila Ryan) is also found brown bread, he'd better get a move on before anyone else ends up toast - including him! What made this a bit more enjoyable is the beefed up role for the usually quite entertaining Blore. Indeed, "Jamison" proves quite adept at a bit of pilfering and mischief-making that might just save the day! Good fun, this one.
