New Additions To The TBR Pile

I did good this week. I received two books by Agatha Christie, each book has two stories, because I am trying to complete my collection of Christie's titles. I bought some when I was a teenager and read others from the library. Now I am trying to complete my collection because I consider them a sort of comfort reads. Not that I have had time for rereading lately, but these are the kind of books I want to have around. The titles I received were:

Murder Is Easy

Ten Little Niggers

Destination Unknown

Hickory Dickory Dock

I was planning to take a picture of my books but I forgot them at my parents so I just picked some covers online and put them here although I must say that mine are in portuguese and don't look anything like this...

While I was looking for the covers I read a bit about each book and I clearly need to reread them as I totally forgot who the murder is in all of them.
