When he gets to London St. Pancras, he would be no more than 1.5-2 miles from Camden Town. He can either take London buses or the underground there. I attach a link to a map on the Transport for London site that shows bus connections in and out of Camden Town. Looks like Bus 46 goes direct from St. Pancras to Camden Town.
