The Rathbone/Bruce Sherlock Holmes series draws to a close with this thriller, in which the great detective and his chronicler race to beat three ruthless criminals to the secret held by three seemingly ordinary music boxes produced in a prison workshop, facing trickery and traps along the way. The final entry in the series is a solid one, with enough action to keep the thriller interesting.

  Recommended. Otto finds this one pleasing enough to relax.

Movie 200 for 2021.
