Death of Suspense is introduced as "A Death who has not previously been identified" when Adam says "The suspense is killing me." in strip 2146, and then sabotages himself in strip 2162 by telling Adam and Jamie what will happen when their dynamite explodes.

There is no obvious difference between Death of Suspense and the previously seen Death of Being Impaled by a Javelin/Death of Annoying the Cartoonist
