In the books
- "Mr. Haverbink was an extraoridanrily large and thuglike man of working-class extraction. What origins his cultivated speech left in doubt, his physical appearance demonstrated. He was the type of good farming stock that, when the oxen collapsed from exhaustion, picked up the plow, strapped himself to it, and finished tilling the fields by hand." (Soulless, Chapter Seven)
- "A werewolf? No, miss. Not interested in being a claviger either, so I shan't ever become one. Gone up against a couple in the boxing ring once or twice, so do not worry yourself on that account." (Soulless, Chapter Seven)
- “Mr. Haverbink bowed deeply, muscles rippling all up and down his back, and lumbered from the room. Miss Hisselpenny sighed and fluttered her fan. "Ah, for the countryside, what scenery there abides..., " quoth she. Miss Tarabotti giggled. "Ivy, what a positively wicked thing to say. Bravo.” (Soulless, Chapter 7)
- "The hugely muscled young man looked like he would prefer to simply pick the Beta up and carry him out to the street, relieving the werewolf of his obvious distress. But, showing he did indeed have experience working with the supernatural set, he respected his superior's pride and did not even try to assist him with an arm." (Soulless, Chapter Seven)
- "Haverbink was a good solid chap in both looks and spirit. And no one would bet a ha'penny on his having excess soul, but he listened well and got around to places more aristocratic types couldn't. He looked a bit like a farmhand, and people didn't give a man of his brawn much credit in the way of brain. It was a mistake." (Blameless, Chapter Fourteen)
- "You better believe if she thought she were in the right, she'd be squawking official statements to the press like a hen laying eggs." (Blameless, Chapter Fourteen)
- "Right'o, sir. I wouldn't want to be in your spats right now.' 'Don't get personal, Haverbink.' 'Course not, sir." (Blameless, Chapter Fourteen)
- Claims to have gone up against a werewolf or two in the boxing ring.
