Collect the body? Take what body? After the main task, you ask Keira, 1. Her task is to remove the curse of the mouse tower. After that, she said that the delivery merchant didn't come to you to find the task of the merchant (you can find it next to the goods when the merchant dies). Finally, she found something to have a candlelight dinner with Keira. After getting up in the morning, she went to the mouse tower. According to the dialogue, she chose Kaika to decide whether to fight with you.

1 If I fight you, you can take her body. If you don't fight, let her go to the white wolf's lair (let her keep those documents, because I don't understand). Tracy will cry whether she will come back and be burned to death or not.

Kayla's tasks are all over, there are three in total, and each task is to complete the last one, and immediately start the next one.

Where can I pick up Keira to help you? After the main task, you will say that you came to find her and went to her cabin to find her.
