I'm reading Bloodline by F. Paul Wilson and came across the following snippet:
Jack needed to read this. He'd have loved to take it home to pore over, but Bolton would know he'd been invaded when he found it missing.
The narration goes when Jack snuck into Bolton's room and now he's looking at the book. Why does the author uses the perfect tense after the modal verb? This way it seems that Jack doesn't want to take it home right now looking at it but wanted to do that in the past
