Blackie at Sea - Greeley, Andrew M.

Bishop Blackie Ryan is no stranger to locked room mysteries. But when his cardinal sends him to investigate some strange happenings aboard an aircraft carrier, this mystery promises to be a tough nut to crack - for the "Langley" has over 3000 rooms and a crew of 6000.
