A fun outing for our sleuthing family; this time they try to thwart a cunning plan to sell secret government radar papers to the enemy. "Charlie Chan" is ably assisted by Mantan Morland and number three son "Tommy" (Benson Fong). There are barely half a dozen cast members, so the result is never in doubt, but this is quite a fast moving little detective mystery with enjoyable performances from all - including some quite funny stuff from Ben Carter.
