There was almost something too eager in the manner in which the shopkeeper and his... friend? His assistant? Whichever... the way this young woman seemed to be trying to assist. It struck Harold as though they would prefer him to leave.
"I do hope I am not intruding; I can come back later if it should be more convenient?" But his curiosity in all of the books suggested was winning out over his sense of gentlemanly conduct, and it was probably noticeable.
"But you do have the most intriguing suggestions." He adjusted his glasses. "An 1841 Ars Arithmantica? I should have thought of all of Cowell's tomes, there weren't any copies of the 1841 editon left, not even in the hands of collectors? A rare find indeed." And, thought Harold, 'coming home with me'. He wasn't ordinarily possessive per se, though he did rather enjoy collecting physical copies of tomes rather than doing research in some musty library, and unless the price were outlandish... he may have just tipped his hand in enthusiasm, but money wasn't everything.
He thought about the next suggestion, "Speech and Symbols in Magic", and had to remark that, "Well, speech and symbology isn't really my field of expertise, though I daresay the resident Hogwarts librarian might have a thing or two to say on the subject, as she is rather fond of make use of runes."
He frowned, "From your description it almost sounds like some of the points raised by Miller in her work on comparing the styles of our magic with practised voodoo in the Americas, and some of her observations about their similarities despite the vastly different cultures." Harold hadn't intended to engage like that, but Miller's book had intrigued him on the subject, and he liked that Miller was a newer author unafraid of challenging the academic orthodoxy.
The name Scrivenshaft seemed somehow familiar, like someone he might have met at a conference. It had been a while since he'd been to one of those. He arched an eyebrow. "Time travel, you say? To me that's the pinnacle of scientific application of arithmancy, and I've long believed we can do more interesting things than time turners." He let himself smile enthusiastically. It's easy to say you believe something when you already know it to be true, after all. And if the man had also written some fiction, well that would no doubt be splendid to enjoy over a lovely cup of keemun.
The last one, suggested by Miss Raveendran had appeal, but less for himself. The title seemed entirely apt for something that might intrigue Msaed, especially if it might offer some thoughts on what to make of Bonnie.
"You've both been so helpful, really quite marvellous... I'd like to take all of them, please." He kept muttering how splendid the service was. He would be recommending this place to Msaed and Rose when he got back to Hogwarts. He was sure at the very least the tales of an umbrella creature would be sure to amuse.
