How does George MacDonald Fraser use imagery in Flashman and the Redskins?

Examples of Imagery:

"Spring grabbed it and jerked—and the cane came away in his hand, leaving the Frog holding two feet of naked, glittering steel, which he flourished feebly with Gallic squeals. Poor fool, there was a sudden flurry, the snap of a breaking bone, the Frog was screaming on the floor, and Spring had the sword-stick in his hand."

"If there's one thing I know, it's when to leave; I was over the counter and through the door behind it like a shot, into a store-room with an open window, and then tearing pell-mell up an ally, blind to all but the need to escape."

"For one thing, the sluts all had their dressing-tables and mirrors and wardrobes, stuffed with silks and satins and gowns and underclothes and hats and stockings and shoes and garters and ribbons and jewelery and cosmetics and wigs and masks and gloves and God knows what beside—there were several enormous chests which Susie called 'equipment', and which, if they'd burst open in public, would have led to the intervention of the police. Gauzy trousers and silk whips were the least of it; there was even a red plush swing and an 'electrical mattress', so help me."
