From the beginning, their only plan was to secure Princess Coreen and nothing else. Spade knew that it was not yet time to go head-on against the organization.
He never hoped that the elite team he deployed would miraculously capture the Marquis at once with his wife; the chances of that happening were not even zero percent.
Spade was aware that there was no way the Marquis would not sense the shift in the air in the capital with his intuition and might make countermeasures for himself. However, he still miscalculated this time. Knowing that they could escape at any moment, he already made preparations beforehand, and some of his forces were deployed earlier on to encircle the possible routes of escape and not far from the Ford Mansion.
He should've known; his opponent was in no way simple. The moment he smelled trouble, he had already disappeared like smoke, leaving blood in his path.
