   Writ of detinue (Law), one that lies against him who
      wrongfully detains goods or chattels delivered to him, or
      in possession, to recover the thing itself, or its value
      and damages, from the detainer. It is now in a great
      measure superseded by other remedies.
      [1913 Webster]

WRIT OF DETINUE, practice. A writ which lies where a party claims the 
specific recovery of goods and chattels, or deeds and writings detained from 
him. This is seldom used: trover is the more frequent remedy, in cases where 
it may be brought.
