At the command center of the Lookout, Chase, dressed in his advanced spy uniform, complete with night-vision goggle and a headset, stood at attention while Skye was zipping up the last attachment on his back. Ryder was busy prepping his Lookout workstation, a mass of monitors and computer systems before a single leather chair.

"Chase, now that it is close to midnight, I will need you to put your spying skills into action." began Ryder, "Your mission is locate Katie at the train station and relay her approximate relative position back to me. If you succeed, I'll send in rest of the Pups to bring her out. I'll communicate with you via radio and tracking your positions on the monitor for the entire time."

"Super Spy Chase is on the case, Ryder sir!"

"And Skye, I will need you to drop Chase on the rooftop of the station with your copter. Stay in the area, as you will bring Chase back once the mission is complete."

"Let's take to the sky!" yelped Skye excitedly, gracefully somersaulting in the air.

"Good luck, both of you. I wish you success." finalized Ryder. Chase and Skye then ran to the elevator and disappeared as it slid down.

Settling back into his leather chair, Ryder donned his own headset and activated the main command monitor and Chase and Skye's tracking device. In no time, he observed two green blinking triangles hovering over each other as they encircled the train station, which was marked with a red exclamation mark.

"They should be going in now," muttered the PAW Patrol leader to himself. He zoomed in closer until he could make out individual seagulls sleeping peacefully on the roof gables.

"I'm dropping in, sir." Sure enough, one of the green dots slowly detached from the other, and planted on top of the exclamation mark. The other green dot waited, then left and glided in elliptical ovals around the train station.

Meanwhile, Chase could feel the beauty of the night. The rare quietness, the twinkling stars, the warm air. Yet he refused to give in; his search-and-rescue mission was much more important and severe.

"Okay Chase, what do you see?" came Ryder's crackling voice.

Scanning around observantly, Chase saw almost nothing out of the ordinary but still decided to report, "There's nothing here except a stairwell and a canvas covering something pretty large. No strange scents. Shall I investigate the roof more, I really would like to see what's underneath the canvas."

"Negative, Chase, we cannot waste precious time. You have to head down the stairwell now."

Putting on his night-vision goggles, Chase's perspective was instantly drenched in various shades of green, providing more clarity but at the same time erasing fine details. Nevertheless, he proceeded to the stairwell, slowly opened the door and went down until he was reached the bottom, which was also behind an empty ticket booth.

"The station is deserted, Ryder. I'm at ticket booth number 8 and will be heading to Terminal 1 to continue the search."

"Got it. Just be careful."

Adhering to the contour of the walls, Chase maneuvered across without hurry. He sniffed the air for scents, while his goggles found and identified distant objects. Suddenly, his sensitive nose caught a whiff of a weak odor of daffodil flowers and blueberry pie. It sent ripples through his body, and a warming sensation exploded in his chest.

"I've got it, I've picked up Katie's perfume scent!"

"Follow it, Chase."

"Will do, sir."

Tracking the pleasant smell of his pet groomer with his face glued to the ground, Chase found himself in front of a green wooden door in a dark hallway. All of a sudden, the spy Pup could hear talking. his ears twitched furiously, attempting at all cost to know what was happening behind the door. It was Katie, and ... Ryder?

Disposing the absurd information, Chase eagerly delivered the much-anticipated report, "Ryder, I know where Katie is kept. I'm planting a listening device near her."

Pulling a listening device from his Pup Pack, Chase placed the bone-shaped contraption underneath an advertisement beside the door, and promptly activated it. A dim green light shone through the poster, blinked rapidly and finally stabilized with faint blue light. A blue bone-shaped icon would now appear on Ryder's screen, recording any audible conversations in a 5 meter radius, even through physical objects.

However much, Chase was reoccupied with the celebration of success that he was't aware of a mysterious presence watching him from the shadows. The presence, the ninja Pup Katie had confronted earlier, got up and started towards him.

Grinning from ear to ear, Chase backed away and glanced at his digital watch. Perfect, an hour before midnight. There would be plenty of time for the rest of his team to get in here and rescue Katie from the kidnappers, "Anything else you want me to do, Ryder?"

"Can you relay tell me her relative location?"

"Oh yeah, almost forgot!" Chase exclaimed, "She's located at Terminal 1, Hall 3 and inside Door Number 10."

"Information received. Good job, Chase, your mission is complete and a big success. Now rendezvous with Skye as soon as possible on the rooftop."

Chase's heart pounded in his chest like a jolly giant. Unfortunately, all that would change. The sensation of happiness and excitement would soon be replaced by the feeling of dreaded regrets as the ninja Pup stood at a good striking distance away from Chase and spoke in a slight French accent.

"Les touristes, including spies, are not allowed, mon ami."

Chase whipped around with his stun gun at ready, only to have it knocked out and a clenched paw smashing into his face. Thrown back, Chase regained his stance quickly and rubbed his new injury, a black right eye.

"Where is Katie?" the spy Pup growled angrily, "Where is she?"

"Who would want to know, mon ami?" The foe wore a black jumpsuit, a balaclava and a red beret, like commandos in the miliary. Yet under the deadly gear was a puppy no bigger or older than Chase. It was the fighting skills of either that decided the fate of the soon-to-be brawl.

The spy Pup charged and threw a wild punch. It was blocked with ease. Chase's goggles, in retaliation, were swiped off clean by a swift kick by the ninja Pup. Distracted by the distruptive sight change, Chase was sent to the ground again by a flurry of well-aimed attacks. He shakily again, only to find the enemy vanished into thin air.

In a flash the ninja Pup reappeared from behind and wrapped strong paws around Chase's neck. the spy Pup, struggling uselessly for a breath, was finally put unconscious by an elbow to the head. Breathing heavily with pride, the Pup bent over and pulled off Chase's headset.

"Hello? Chase? Is that you?" Ryder called out frantically from the gadget. The moment of zero communication between him and Chase would surely have caused panic.

"Negative, mon ami," replied the ninja Pup calmly as he toyed with the headset. There was a brief silence, and then he finished his sentence.

"Your spy chien is in our hands, mon ami. You've underestimated out abilities." Before the PAW Patrol leader could respond, the headset was violently stomped on until it was no more.

Dragging a comatose German Sheppard with him, the ninja Pup caught sight of a blinking light an ad poster. Giving his wrist computer a nudge, a shuriken launcher was produced out of his Pup Pack. It fired a silent projectile, whizzing through the air at incredible velocity. The poster glided to the ground, shredded into pieces, and revealing a mauled bone-shaped device.

"Amateurs." scoffed the ninja Pup. There would be no remorse tonight.
