Pre-viewed for quality and there was a quick line at 1 hour 10 1/2 minutes and then rolling lines at 1 hour 14 minutes. Otherwise it played fine on my Sony vcr deck and the cassette is nice and clean. Box has been cut neatly and mounted in a white, hard clamshell keepcase. The USS Tigershark is a submarine in trouble. The captain has been lost overboard and tempers run high in the confined spaces. Then the sub rescues three drifters in a life raft, one of them a woman, whose prescence on board is agreed by everyone to be bad luck on a sub. The sub is tracked by Germans, who drop depth bombs and later come back to troll for it with giant grappling hooks. There is fearful damage to the periscope and control tower. An oil leak threatens to betray the subs position. Oxygen is running low, and hydrogen in the air is a danger to the crew's safety and sanity. And perhaps there is... a ghost on board. The creepy sounds from outside the hull--of seaweed, whale songs, and bouncing depth bombs--increase apprehension. Yes, a ghost! How else to explain why a record of Benny Goodman's "Sing, Sing, Sing" seems to play itself at inopportune times--as when the Germans are listening for the slightest sound from BELOW? And when the late skipper was a Goodman fan? Of course, there could be a saboteur on board, in addition to, or perhaps instead of, the ghost.
