Someone has been killing passengers on the express train from Lisbon to Porto, every single day since Tuesday! Someone needs to stop the killer! Once again Garcia is not up to the task (was he ever?) and reluctantly calls upon his old friend and his strange flying sidekick: the mythical Detective Case and the unmistakable Clown Bot. Together, they will board on the express train, bother everyone by asking annoying questions, pick up everyone’s belongings and call them clues, drink and eat for free at the bar (because they are working after all!) and if all goes well, find and stop the express killer. Oh, and they have to babysit Garcia’s kid because his mom is in Porto and Garcia is busy and since they are taking the train to Porto they might as well take him with them. What could go wrong, right? Time for you to board on a brand new adventure filled with humor, cases (this time many cases!), mysteries, and even more characters now than ever before! Will you be able to gather clues, solve the puzzles, succeed the trials, and find the culprit before reaching the final station?!
