I'm reading Antonio & Jonna Mendez's The Moscow Rules, about the difficulties and triumphs of running a spy network in Moscow during the Cold War. You may remember Antonio Mendez from the movie Argo:
You may remember his wife Jonna from a post I put together a short while back about disguises:
This isn't a review, so I'm not going to say much about the book, except that I recommend it wholeheartedly.
One of the stories it tells is that of Russian diplomat turned CIA asset Aleksandr Dmitryevich, who died by suicide after being taken by the KGB. He used what was called an L-Pill to do it, hidden in his pen.
It occurred to me that Night's Black Agents, and the assets they run, face a peculiar dilemma in their line of work. An L-Pill, or in this instance a D-Pill, is no guarantee.
The whole point of killing yourself in these unhappy circumstances is to avoid interrogation. However in a world where vampires exist, death is no defense at all. Whether Damned, Supernatural, Mutant or Alien, there's every possibility that a dead agent can be revived, or their soul preserved through necromantic or alien scientific means. So they can be interrogated - perhaps forever.
This is something that's bound to prey on the minds of Network contacts. A player character is probably happy to take that risk, but a Network asset doesn't have to be so self-sacrificing. That person would probably like a way out, if the worst happens. The problem is, how to achieve that?
Polluting the body, perhaps with a substance like Polonium, which in theory ought to render the victim a form of immunity from vampire attack. No bloodsucker is going to want to tap that glowing keg. However there are two obvious problems here. The first is that a substance with that level of lethality is difficult to manufacture, transport, and use. In the case of polonium, even standing near the substance is enough to leave potentially lethal traces.
The second is, it doesn't kill you quickly enough. There's no point rendering yourself immune to vampire attack, if you leave yourself wide open to conventional interrogation.
Using a conventional poison in combination with vampiric banes or blocks, perhaps by eating garlic every day in anticipation of the final event. That's probably going to have complications unique to that particular bane - 'why does Natasha always smell like garlic pizza?' However it does rely on accurate Vampirology. If garlic doesn't actually work, then all that pizza smell was for nothing.
It may also be that the concept of a D-Pill negates the bane. Suicide is a sin. Holy water used in combination with a D-Pill probably won't work, since the sin negates the water. It might be catastrophic in certain circumstances, particularly with Supernatural or Damned vampires. If you end up in Hell, there's a decent chance your former enemies can visit you in your eternal torment, and, as Hellblazer's Ric the Vic discovered, easily break you.
Dying in such a way as to reduce the possibility of necromantic or scientific revival. They can't put your brain in a jar if you go up in a glorious napalm fireball. While this has some merit, it lacks the convenience of a D-Pill. It depends on specific circumstances to work, where the L-Pill's utility comes from being able to use it wherever, whenever. Dmitryevich had already been captured, stripped all but naked, and was being forced to write his confession when he got his hands on his L-Pill.
No, the plain fact of the matter seems to be that a conventional D-Pill is out of reach, without accurate Vampirology and a convenient, ingestible Block or Bane. However there is one possibility, and while it won't negate revival, it might provide a certain comfort.
Use a radioactive tracer. That way, at least your allies will be able to find your body. Heck, there's a decent chance you may be able to spread the substance to your attacker, giving your allies a chance to find whoever did you in before they can give away vital intel to your enemies.
It's not a D-Pill, but it's better than nothing.
