I'm currently reading 1984 by Orwell to improve my verbal section (well, I constantly read but this time I've been paying attention to the actual structure) and have found this sentence.They had confessed to intelligence with the enemy (at that date, too, the enemy was Eurasia), embezzlement of public funds, the murder of various trusted Party members, intrigues against the leadership of Big Brother which had started long before the Revolution happened, and acts of sabotage causing the death of hundreds of thousands of people.
There is an example of which: the clause "had started long before the Revolution happened" is not important and can be omitted so we use "which". Then there's parallelism: they had confessed to intelligence, the murder, intrigues and acts of sabotage. Plus a modifier "causing death" and tenses: even though the main sentence is in Past Perfect we use Past Simple in the brackets because Eurasia was the enemy for quite a while.
Or another one with two modifiers both starting with which.After confessing to these things they had been pardoned, reinstated in the Party, and given posts which were in fact sinecures but which sounded important
So here I am lulling myself into thinking the reading is not just for leisure
