In The Markenmore Mystery (1922) by J. S. Fletcher, Blick, a detective-sergeant, was thinking about the way by which someone had entered and left Markenmore district. Firstly he studied the railways and trains, and then he turned to studying the roads and motor-cars.
And on turning to his time-table, Blick discovered that between four and six o’clock in the morning, there were, taking these four stations altogether, a respectable number of trains going north or south, east or west, and that from two stations, the junction aforesaid and the one to the north, there were at a quarter to six every morning, workmen’s special trains, which doubtless conveyed large numbers of craftsmen, artisans and labourers into the big shipping port a few miles away on the coast. Altogether, he saw that a smart, astute man would have no difficulty in getting away unobserved from the Markenmore district by an early morning train, in any one of at least six separate directions.
Turning again to the question of access and excess by the roads, Blick remembered what Walkinshaw had said about the facilities which the district afforded for successfully hiding a motor-car while its owner or occupant paid a visit.
The whole context and the previous discussions spoke of "entering the region and getting away from it", and "access" may mean "enter", so can "excess", by any chance, mean "exit" or something like that? or does it simply mean "crossing the boundaries of the region"?
