When an enemy makes overtures of friendship, is anyone safe?

An unexpected invitation from wily King Frederick causes composer Joseph Haydn to fear he's walking into a trap. After all, the Prussian King has never had any use for Haydn's music. His Majesty seems more intrigued at Haydn's being the son of a market-judge.

Worse still, the invitation appears to stir up suspicion in the highest quarters in Vienna. So much so that a mysterious, cloaked lady visits Haydn's Music Room and issues a thinly veiled threat.

Now Haydn is convinced there's mischief afoot. But not even he can foresee that he will stumble upon the corpse of the imperial ambassador a day after his arrival in Frederick's Prussia, along with evidence that His Lordship may have been a common thief.

Can Haydn salvage the imperial ambassador's reputation—and find his killer?
