1976 - SHERLOCK HOLMES: Interior Motive

A Kentucky Educational TV Production

Sherlock: Leonard Nimoy
Dr. Watson: Burt Blackwell

Sherlock Holmes and Dr. Watson receive a globe and a letter. 
Holmes orders Watson to read the letter again: 
"My secret within you must seek out. 
But spare my skin or break my heart." 
No signature given. 

After Holmes had left in the morning and before the paper boy had come, he found the globe in front of their door. Watson urges Holmes to throw light into the riddle – before the royal society will be at their home tonight. Their first findings tell them that the inside material must be heavier than the outside material. "It does not tell us very much," Watson remarks. "Then we have to learn more," Holmes responds and checks on the temperature inside through a little hole. Now Holmes tries vibrations which he divides into primary and secondary vibrations. The primary vibrations going through gasses, liquid, air and solids, the secondary through solids only. 

For his nephew's birthday Watson has bought a compass. As he unpacks it, he wonders why it is not showing north but to the globe. Holmes finds the missing piece and promises him the answer tonight when the royal society will be in. Before them Holmes explains how he came to the solution: The difference in the way of the waves gave him a clue where the cord is. The temperature and the magnetic field what the core is about: Hot melted metal. As they applaud, Holmes refuses the praise at first because the real answer is that in the core a detective is a scientist and the scientist a detective. Now he accepts the applause. When all have left Holmes admits that he has not solved the final question: Where it had come from.
