- He had a large, square face, skin the color of polished onyx.
- He was an enormous man, a full six foot six and two hundred sixty pounds of solid muscle, with hands the size of steamship rounds.
- A lean man who favors good suits.

- Although the Chief's position is political, Tibble remains a cop.
- He has no patience for bullshit.
- His temper is like a "furnace blast", but he blows off steam and again becomes cool and contained.
- Tibble had risen through the ranks.
- He'd plodded his way up from beat cop.
- He worked the West Side barrios when cops and their quarries still carried guns.
- He'd taken a hit once, before the gun ban: three nasty rounds in the abdomen that might have killed a lesser man and would certainly have given most ordinary cops cause to consider their career choices. Tibble had been back on full duty within six weeks.
- After the gun ban, he'd used his bulk and cold, terrifying grin to intimidate his quarries.
- He still had the mind of a street cop, and his record was clean enough to serve tea on.
