No, it isn’t a Knifey Moloko high-ball. The author of “A Clockwork Orange” Anthony Burgess left us few clues except that one of the main ingredients is milk and probably barbiturates to taste, but this drink isn’t a bad replacement:

• 1½ oz gin
• 1 oz Irish whiskey
• 1 oz fresh orange juice
• ½ oz fresh lime juice
• ½ oz simple syrup
• 2 or 3 dashes Miracle Mile Chocolate-Chili Bitters
• freshly grated nutmeg

Fill a cocktail shaker with ice, gin, whiskey, orange and lime juices, simple syrup and bitters, shake, strain into a chilled coupé, garnish with nutmeg and serve.
