Nightwing #106 (2023)

NIGHTWING GOES NAUTICAL! Sail the high seas with Nightwing and Batgirl as they journey across the ocean in search of the Hold's secret society that dates back to when Blüdhaven was founded. We saw previously in Nightwing #99 that the Hold’s vault held several safes... and here we'll find out there has always been one left for Nightwing.
