Skull Duggery, by Aaron Elkins

Just downloaded this for my Kindle today, and am about to start reading it.

But I thought... skullduggery - just where does that name come from?

Here's what Dictionary.com has to say:
1. dishonorable proceedings; mean dishonesty or trickery: bribery, graft, and other such skulduggery.
2. an instance of dishonest or deceitful behavior; trick.
Also, skullduggery, sculduggery, scullduggery.

Origin:
1705–15, Americanism ; var. of sculduddery, orig. Scots: fornication, obscenity < ?

So it has nothing to do with digging up and faking skulls. ; )
