The dogs had many tricks.

They knew the terms of drill as well as any soldier, and were always ready for parade, or to die for their country, or groan for their country's enemies, at the General's word of command.

Nelly had to be much out-of-doors, as the dogs were clamorous for walks, and she kept her roses in London with the old milkmaid sweetness.
There was one happening of the quiet day that stood out for Sir Denis, and, although he did not know it, for his daughter also.
Sir Denis's old regiment happened to be stationed at a barracks in the immediate neighbourhood.

To reach their parade-ground it was possible for the troops, by making a little detour, to pass along the quiet street on which the houses in Sherwood Square opened.

It became an established thing that they should pass every morning about nine o'clock.
