As best as I can guess, this is a cocktail made by or for its namesake, a contemporary author of a series of mystery novels. If that is the case, I bet there's a Nathan Wilkinson cocktail out there somewhere (there isn't) if I google myself. 

But I like the style of this cocktail, which resembles a Vieux Carre. The main ingredient is Swedish punsch, which is spiced with clove and cardamon. My homemade punsch is made with a spirit blend of half dark rum and one quarter each of MurLarkey distillery lemon and three tea whiskies. That means that there's citrus, earthy and floral tea notes, and dark sugar and oaked rum spirits. It's a cocktail in itself, but it is smothed out with a little cognac and helped along with more spice from Angostura bitters.

• 2 oz. Swedish punsch (homemade used)
• 1 oz. cognac (Martel single distillery used)
• 2 dashes Angostura bitters
• lemon zest twist

Combine all ingredients except lemon twist in a mixing glass with ice. Stir and strain into a chilled cocktail glass. Twist the lemon zest over the glass and drop it in.
