Chapters 15-16 Summary

Neidelman is pleased that Malin likes his office and the progress they've made on the island. He leads Malin to a hole where several engineers are working. Neidelman shows Malin a computer printout and says the text results indicate that this hole is the Water Pit. It has been verified by carbon 14 tests that pinpointed the date of the wood. When the tide comes in, they plan to dump a high intensity dye into the Water Pit and see where it appears in the water outside the island. This will help them find the floor tunnel which they will seal with explosives. This will keep the Water Pit from flooding and allow them to work in a more manageable environment.
