What is an example of imagery in the novel, The Murder of Roger Ackroyd?

Imagery:

“Ackroyd has always interested me by being a man more impossibly like a country squire than any country squire could really be. He reminds one of the red-faced sportsmen who always appeared early in the first act of an old-fashioned comedy, the setting being the village green. They usually sang a song about going up to London.” pg. 7

“It was indeed a beautiful object. A narrow, tapering blade, and a hilt of elaborately intertwined metals of curious and careful workmanship. He [the Inspector] touched the blade gingerly with his finger, testing its sharpness, and made an appreciative grimace. ‘Lord, what an edge,’ he exclaimed. ‘A child could drive that into a man – as easy as cutting butter. A dangerous sort of toy to have about.’” pg. 64
