Once she knew he was ok and he waved her off she focused on her part of the plan. Her pack was set on Howe's desk and she started removing the various tubes and containers that held the explosives. She'd been careful, testing the charges out on the land that surrounded the castle, working with the materials, the colors, the timing, until she felt comfortable putting both her and Lucky into harms way.
Even though she'd looked at the plans of the building she still took an initial walk around the edge of the room. Each wall was touched and knocked, at one point she even leaned into one and held her ear to it, listening.
Then she went back to the desk and picked up the container holding the blue clay. She set those on the outer walls, paying close attention to the windows and setting at least one, small, extra charge at each one, it wouldn't do a lot of damage to the walls but it would toss a nice fireball out the windows.
Once the blue charges were set she picked up the container that held the green clay. Those were less powerful and were for the interior walls.
When she was finished she slowly turned and looked at the charges, smiling a little. The interior ones might scorch the walls of the adjoining offices but she was confident there wouldn't be any damage done, well any damage that couldn't be fixed by a can of paint anyway.
The last container held a large mound of white clay, "Yay for good." her answer to his reply was muttered. She was distracted and concentrating on what she was doing.
Next she reached into her bag and pulled out cylinders filled with gelatin looking balls in blue, green, and red. Blue were placed around the blue clay, green were placed around the green clay, and red were set around the white.
She finished with a smile and turned to look at Lucien, "Ok, almost set. The blue are the stronger charges, the green are weaker so I put them on the interior, the white will take care of all the paper's in the office. Once we place the calling card orbs" We have 15 minutes to get out. Think we can do that?" her smile grew as she finished speaking, she was having fun, a lot of fun and since they hadn't gotten caught yet she was letting it show.
He drew a deep breath, pushing up from the chair and nodded in reply to Kate. He reached into the pack and pulled out a white feather then secured the pack, and the documents they'd found. "Yes." The tone of his reply left no doubt he wanted the demon to pay. Another assessing glance was swept over the office as he step out from behind the desk. "Where did you want to leave the calling cards?" he queried Kate, absently twirling the feather in between his fingers.
Her smile grew more wicked as she pulled out the tube of clear orbs, "I'll leave one in the middle of his desk, one by his door, and one at the front desk. I suggest you put yours at the front desk, unless you think it would survive the explosion?"
She watched him pick up a book off a shelf, one eyebrow raised but she didn't say anything to him, she just waited for his answer, "We'll leave it at the front desk then. Ready?"
And that was what she was waiting for, she turned and set two of the clear orbs on Howe's desk, one on either side of the white lump of clay. "Yep, lets blow this joint." Her joke had her s nickering as she left the room, dropping another orb just inside the doorway of the office.
She set the last two orbs on the front desk and smiled again. "All done. Shall we stroll on out of here?" She started moving toward him then frowned. "Damn, forgot my pack. Hold on." With one finger held up she walked back into Howe's office and to her pack on the desk.
