"The Secret of Phantom Lake" by William Arden is a vintage 1979 paperback novel from the Alfred Hitchcock Three Investigators series. The novel is published by Random House Children's Books in the United States, making it a collectible item for fans of mystery and juvenile fiction genres.

This paperback book is in fair to good vintage condition.

The book has age-tanning/foxing/yellowing to the pages and covers, small crease on the front cover, the spine is intact. 

I found no owner initials or marks in the book; there is a faint smiley face stamp on the inside 1st page. 

Some markings on the edges. 

Please refer to the photos to confirm the condition of the books and let me know if you have any questions prior to purchasing.

Thanks for your interest
