Nitric acid
Nitric acid (HNO3), also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid.
The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as white fuming nitric acid or red fuming nitric acid, at concentrations above 95%.
Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent.

Beanball
"Beanball" is a colloquialism used in baseball, for a ball thrown at an opposing player with the intention of striking him such as to cause harm, often connoting a throw at the player's head (or "bean" in old-fashioned slang).
A pitcher who throws beanballs often is known as a "headhunter". The term may be applied to any sport in which a player on one team regularly attempts to throw a ball toward the general vicinity of a player of the opposite team, but is typically expected not to hit that player with the ball.
In cricket, the equivalent term is "beamer" or "bodyline".
Baseball
In baseball, a beanball is a pitch, similar to a brushback pitch but actually intended to hit the batter as it is thrown at the head. It is rarely used as a strategic weapon, and is usually an act of anger and frustration; however, batters facing known headhunters are given a reason to fear a beanball and may alter their approach to hitting in the interests of self-protection, perhaps giving some strategic advantage to the pitcher. Some pitchers have been known to throw beanballs in response to giving up home runs. Teams with heated rivalries often find several beanballs exchanged in a season.
Michael Slade
Michael Slade (born 1947, Lethbridge, Alberta) is the pen name of Canadian novelist Jay Clarke, a lawyer who has participated in more than 100 criminal cases and who specializes in criminal insanity. Before Clarke entered law school, his undergraduate studies focused on history. Clarke’s writing stems from his experience as a practicing lawyer and historian, as well as his extensive world travel. He works closely with police officers to ensure that his novels incorporate state-of-the-art police techniques. Writing as a team with a handful of other authors, Clarke has published a series of police procedurals about the fictional Special External Section (Special X) of the Royal Canadian Mounted Police. His novels describe Special X protagonists as they track down fugitives, typically deranged murderers. Four other authors have contributed under the name Michael Slade: John Banks, Lee Clarke, Rebecca Clarke, and Richard Covell. Despite the collaborative nature of the books, Jay Clarke is the predominant voice in their writing. Currently, Jay and his daughter Rebecca write under the Slade name.
