Sat and read through Hellboy: Into The Silent Sea this evening. Awesome! It's only a 56 page tale, but it's pitch perfect. After The Island, Hellboy drifted on the sea for a time before arriving in England. This is at least one of the bizarre adventures that happened to him during that time. It's basically the usual Hellboy template but there's some surprising call outs to the greater lore and Gianni (whom I'm not familiar with at all) pencils the whole crazy thing to great success and Stewart nails it as always.
It's cool to finally see what happened after that tease at the end of The Island all that time ago, and with The Visitor's story also being told, I kind of feel like I've nearly had every big question I genuinely wanted to know about HB's adventures answered. That's not to say there isn't endless room for Mignola to tell these kind of small adventures, but it's just cool to have so much addressed. Would still love to know what happened during HB's first visit and lost week in Africa that led to the ominous warning in Strange Places though, that one is still there.
