A dead body has been found on board a ship, and all passengers seem to have an alibi. Luckily several professionals are on board willing to help, but can you trust them? By asking clever questions and using deductive reasoning, you just might manage to expose the missing alibi and identify the murderer. Perfect Alibi is a classic deduction game in the tradition of Sleuth. However, Perfect Alibi has a shorter playing time, and unlike other deduction games some of the information you get might be false. Finding out who is lying to whom is therefore crucial, and you must take full advantage of the abilities of several available assistants to gain the information you need.
