Not so much an adventure as a multiple-choice novel, the story concerns your mission to deliver a letter to England that will prevent the Queen from being discredited by Cardinal Richelieu for giving the Duke of Buckingham some diamonds.
Text narrative alternates between choices and action. These are in most cases displayed sequentially, and selected by pressing RETURN. In some cases, the range is limited to a choice of two actions, and those presented are rather contrived. For example, when charged with your mission, do you rush off by jumping out of the window, or hurry through the door?
Very little gameplay is somewhat offset by some effective graphics, in most cases digitised from photos.
There is a terrible dirge that accompanies the whole game, but this can easily be turned off, and probably will be.
It is not an orthodox adventure.
