Why The Vanishing Act Matters in This Noir Action Game
The Vanishing Act is the first full case in Mouse: P.I. For Hire and the mission that proves this noir action game is more than a clever gimmick. You step into Jack Pepper’s tiny shoes as he’s called to investigate the mid‑performance disappearance of magician Steve Bandel, a mystery that quickly hints at darker forces at work. The case pulls you through a crime‑scene theater, cramped apartments, and grimy streets before looping back to your office to connect the dots on the Crime Wall. Because investigations in Mouse: P.I. overlap and feed a larger conspiracy, skipping clues here weakens the story payoff later. This Mouse PI walkthrough keeps the focus on fast, fluid gunplay and clean navigation: you will know exactly where to go, which evidence matters, and how to grab essential Mouse PI collectibles without slowing the pace or draining the tension out of the run‑and‑gun flow.

Backstage Break‑In: Theater Entry, Tank Trick, and Greenroom Clues
The case opens outside the locked‑down theater with Wanda Fuller by her car. Take the photo she hands you and head through the left door to the officer guarding backstage; present the photo as a fake ID to gain entry. Before you rush the investigation, loot the locker on the right side of the hallway for Newspaper 1, an easy‑to‑miss Mouse PI collectible. Ignore the nearby locked door for now and slip through the open door on the left, where a vent grate is already removed. Crawl through to reach the stage. Climb the ladder beside the large water tank, drop inside, and grab Bandel’s Greenroom Key. Hit the switches in this room to unlock the stage doors, then return to the previously locked greenroom. Inside, open the vanity table drawer for the address book and photograph the Steve Bandel poster on the wall; both are mandatory clues for your Crime Wall later.
From Greenroom to Streets: Typewriter Save, Early Collectibles, and Alley Combat
Leaving the greenroom, you will find the officers gone. Crouch under the crime‑scene tape and use the typewriter to bank your progress before things heat up. Two bat‑wielding thugs rush you in the next room; hug cover and use quick headshots to preserve ammo. Follow their path up the stairs and, before exiting, loot the table on the right for the Charlie Pepper Baseball Card. These Mouse PI collectibles also feed into the Baseball Cards mini‑game at the bar, where you can earn Spike-d Prize Tokens later. Step outside and prepare for a pincer attack: enemies spill from north and west garages, mixing bats and guns. Prioritize gunmen first while kiting bat carriers into tight lines of fire. Both garages hold Heal-D bottles and ammo; the north one hides a safe you can tailpick for extra cash. This encounter showcases ideal Mouse PI tips: control angles, exploit cover, and keep moving.

Apartment Building Route: Loft Key Puzzle, Secret Schematic, and Fast Exits
Inside the apartment building, sprint upstairs until the first landing, then kick out the window and crawl onto the ledge to reach a blocked room. Grab the Joel Blunt Baseball Card and loot the open safe before climbing higher. At the next landing you will see a locked Loft Key door on the right and a blocked door on the left. Kick the obstruction aside and enter to spot a cheeky poster about barrels, hinting that “totally normal walls” are breakable with explosives. In the nearby bathroom, the Loft Key sits on a small table by the toilet. A box keeps the door from opening fully; shoot it, then blow up the explosive barrel to smash through the hidden wall and open a shortcut back across from the loft door. Crouch under the boards in the loft and grab the Schematic from the desk, securing a valuable secret with minimal detour.

Finishing the Escape: Environmental Kills, Tricky Triggers, and 100% Runs
Returning to the main hallway, take advantage of the environment to keep the noir action game momentum high. You will see an enemy standing under an anvil suspended by a rope; shoot the rope for an instant kill and a satisfying cartoon death. More foes push in as you move toward the alley. Instead of wasting ammo, chain explosions from the barrels outside to wipe groups quickly—especially on higher difficulties. If progression seems stalled later, double‑check you photographed the Steve Bandel poster and picked up the greenroom address book; missing either prevents proper Crime Wall updates and is a common trigger issue. For 100% or replay runs, use this The Vanishing Act guide as a checklist: Newspaper 1 backstage, both early Baseball Cards, the loft Schematic, and the safe pickups. Once those are secured, you are free to sprint the objective line and fully enjoy the smooth, cinematic Mouse PI gunplay.
