A Japanese ship is on route to Kolkata in the Bay of Bengal. Seeking the silent waves, the captain decides to take a nap. However, is murdered while sleeping. When the ship reaches the shores of Kolkata, the city in the West Bengal of India, the famous Indian detective Byomkesh Bakshi is called to investigate the murder of captain. He reaches the ship immediately and after doing initial investigations, he shortlists four crews members as suspects for this murder. These four members are called immediately and he asks each of these crew members that what they were doing during the time when the captain is murdered?
Following are the answers:
1. Hideaki, the Cook: I was in the kitchen doing the cooking.
2. Rokuro, the housekeeper: I saw that the flag hoisted on the ship was upside down, so I went to correct it.
3. Ken, the engineer: I was in the generator room, checking the generator.
4. Takeshi, the second housekeeper: I was tired and taking a quick nap.
Byomkesh Bakshi immediately knew who the murderer was. Can you tell?
