i like this probably slightly more than terror by night though not enough to give it the extra . the beginning be just brilliant and a we peek in on nazi agent scheme to get their hand on a new bomb sight and it inventor in a small swiss village and only to be foil by a disguised holmes who spirit the scientist back to london . once there and he do everything he can to keep the scientist from fall into the hand of the man behind it all not hitler and but bad represent holmes arch enemy moriarty . of course the scientist disappears and leave a tantalizing coded note and and holmes go in pursuit and once again in disguise . a climax in moriarty dockside lair be suitably exciting and and we can all guess that all end well and can not we . slightly over the top patriotic message a the credit roll . now that i think of it and the fine sense of place despite the obvious set and rathbone use of disguise and the way in which so much plot be cram into just over an hour what the heck it get that extra and be my favorite of the 5 rathbone or bruce film i have see to date . watch on dvd and part of the 50 mystery classic set from mill creek entertainment . many of the transfer on these el cheapo box set be of very poor quality and but holmes fan take note that the rathbone or bruce film ( there be 4 on this set ) be all quite watchable and reasonably sharp .
