I'm reading "
Purple Cloud," by
 M.P. Shiel. 
This is a very old book that reads VERY well.  It has some wonderful descriptions of dead people and is a creepy read.  (I do NOT recommend this book for anyone over 70 - the descriptions of dead people could lead to one's demise.]
I'm only on page 60 and looking forward to the rest of it.
Lovecraft thought highly of it and since he thinks like I do, Lovecraft is a very wise man for sharing my same high standards.
