Character summary in a sentence

Another in our ongoing series of gems of the type, this one found by Val:

The Lieutenant by Kate Grenville - set in New South Wales in 18 century - I'd recommend that as well if you come across it. The eponymous Daniel Rooke goes to Australia as an astronomer - a very sympathetic character but he's better with numbers than with people:
'Rooke could hear how his words laboured. He sometimes thought that he arrived at a sentence the way other people did multiplication: the hard way, by adding.' Worth reading the book just for a sentence like that.

Reminded me of the narrator of "Curious Incident"...
