I understand "as" as in the process of. In this case, it would be
"in the process of escaping" which means he'd not gotten away though he was trying to.
Thanks for the period advice. I have been having that problem recently because it takes
really 10 full seconds for the letters to show up on my screen. A
lot of times, I correct only the critical typos because each time i do that
it takes 10 sec to refresh. I can't wait to get my new laptop back from repair.
It's killing me.
