The Black Tulip
8. An Invasion
The incident just related was, as the reader has guessed before this, the diabolical work
of Mynheer Isaac Boxtel.
It will be remembered that, with the help of his telescope, not even the least detail of the
private meeting between Cornelius de Witt and Van Baerle had escaped him. He had,
indeed, heard nothing, but he had seen everything, and had rightly concluded that the
papers intrusted by the Warden to the Doctor must have been of great importance, as
he saw Van Baerle so carefully secreting the parcel in the drawer where he used to
keep his most precious bulbs.
The upshot of all this was that when Boxtel, who watched the course of political events

"And, as I am a good citizen, and as it is the duty of every good citizen to inform against
the bad ones, it is my duty to inform against Cornelius van Baerle."
Specious as this mode of reasoning might sound, it would not perhaps have taken so
complete a hold of Boxtel, nor would he perhaps have yielded to the mere desire of
