Jonas Watcher had no memory of how he got there. As he started climbing up the ladder to the wharf, he found he was tangled in some sort of net. Suddenly a large heavy object dropped onto him and he fell into the bay still snared by the net, which had also captured the object. Luckily, the weight of the object had tightened the net, so he was able to pull himself out of the water and climb up to the wharf.
