Eawdon Wells or Sir Ia wdon's father
had done it. could have fitted the hid

This was one OF the first questions

stopped to think consecutive thoughts
again. And, though he had no answer
ready. he was strangely sure that
Ra Wdon Wells had not lied to him

him Could some outsider have dis

was one utsider who-Dagon was OBJ
so. And II would not have been i'm
possible for that person to make such

Not only was Dagon certain whera
he must seek for the way into the hid

The old house was dark and very
quiet. 1t was an hour when those

detective had purposely waited until
