"Solve this problem with 3 different algorithms with Python and please tell me which is the most efficient algorithm and why."  

The Mystery of Marshall Mansion Murder Last Christmas, I was invited to the Marshall Mansion by Lashram Rivers, a friend I had met a few months before at another friend's wedding party, for a private dinner since I just moved into the city and had no one to celebrate Thanksgiving with. Rivers was adopted by Mr Phillip Marshall, the mansion's owner, when he was 8 years old. Mr Marshall is a wealthy businessman who runs several manufacturing factories all over the US, and Rivers helps manages the business for Marshall. Close families and friends attended the dinner. Mr Marshall's children, Jones and Jenna Marshall, his brother and sister, Peter and Penelope Marshall, his uncle Will Marshall and several other close friends of the family; around 15 people were eating at the large dining table that night. The dinner was wonderful, with plenty of food to eat. But suddenly, in the middle of the desert, Mr Marshall gasped and fell off his chair. Everyone was panicking, and I ran to Mr Marshall to see what could be done. A few minutes later, while waiting for the ambulance, Mr Marshall was not breathing anymore. Part 1: Who poisoned Marshall? A few moments before Mr Marshall passed away, he whispered, "I know who did this". As a detective who works for the Police department in this city, I realised this was not an accident; instead, someone had murdered Mr Marshall. After the mansion was closed for investigation and everyone had left, I started looking for clues. The mansion was a big building with many rooms over a huge land and a lake, and I managed to get a layout of the building (Figure 1) and the surrounding areas (Figure 2). The main building must have some clues, so I will search all the rooms.
