Dept. H #4

This volume collects issues #15–20 of Matt Kindt's underwater mystery series, as the crew of the deep-sea research station faces the final, desperate struggle for survival. With the station collapsing and the killer still at large, the remaining characters must confront both the physical dangers of the abyss and the psychological tensions that have been building since the beginning. The 'Lifeboat' arc brings the story to a tense, claustrophobic conclusion as the truth behind the sabotage is finally revealed.
