This Potion is DA Bomb

Yay first Queen's Own case! Yay first international case! Blowing people up with bombs, not so yay.
 
This is supposed to be a murder-suicide but the case smells. And not just because the dead potion maker lacks knowledge about the cure he supposedly created. Jamie’s got a smoking crater of an office (and body), a queen breathing down her neck, a witness clinging to life, and no answers.
 
One thing she knows for certain, however–this potion is a cure to die for.
