William H. S. McIntyre (born 25 March 1960) is a Scottish novelist whose novels mix comedy, legal procedure, social comment and action.

Robbie's office is situated in the Royal Burgh of Linlithgow; not a stone's throw from the birthplace of Mary Queen of Scots, but the action takes place throughout Scotland and further afield.

One gets the distinct impression that McIntyre is not only writing about what he knows, but from the heart and, probably due to his own experiences, can't resist the occasional dig at the Scottish Government and what he sees as its constant meddling with the criminal justice system.

The books have been well received by many fellow professionals, on both sides of the Bar, due to their accuracy in law and procedure and the main character's frank, if sardonic, view on the idiosyncrasies of Scots criminal justice system.

Written by McIntyre's alter ego, a character from the fictional Best Defence Series, this is a guide to some of the best and most readily available Scots single malt whiskies.
