Inventor of strange tales (5)
I believe the answer is:
tesla
'inventor' is the definition.
(scientist Nikola Tesla)
'strange tales' is the wordplay.
'strange' indicates anagramming the letters.
'tales' anagrammed gives 'TESLA'.
'of' acts as a link.
(Other definitions for tesla that I've seen before include "Nikola ---, electricity pioneer" , "Inventor" , "SI unit; steal (anag.)" , "Physicist" , "Unit of magnetic flux density" .)
