This next by the 10's features a DC "mystery" title of sorts that really changed course a few times... House of Mystery!

Issue 10 here, and it's pretty tame stuff, as you can see.

Issue 20 features Mister Mortem... whom I've never heard of before! While it appears from this cover DC was trying to create a recurring character, I can't find any record that he appeared anywhere other than this issue!

Issue 30's cover is pretty bizarre (well, I guess not so bizarre for the Silver Age)!

Issue 40 -- wow, who would've thought a Scrabble knockoff would be so deadly?

Issue 50 here, but I'm not going to mention the cover... just point out the blurb on the bottom, "I rode the Man O' Mars!" -- now, that's an out-of-context phrase that would have a double meaning as this series progressed, eh?

Issue 60... what did he see in that yellow cloud?

Issue 70, and we've gone from stories of suspense to pure sci-fi!

Issue 80... did Robby Read feature this Big Giant Hand in Dial B for Blog?

Issue 90... wow, what a weird cover, eh?

Issue 100, and that's a pretty strange creature there, isn't it?
What will the next 100 issues bring? Wait and see!
