Alfred Hitchcock and the Three Investigators in The Secret of Phantom Lake by William Arden.  Published in 1974 in hardback by Collins, 1^st UK edition. 

This is an ex-library copy that displays not too badly.  The boards are in reasonable condition with some wear at corners and base, see pics.  Internally, the book is complete with the usual library stamps etc.  Not a bad copy this, and it will certainly plug any annoying gaps in your collection.

Dotch verdict:  I went looking for some nice Three Investigators books this week and found a whole bunch of them in shall we say less than mint condition.  Check out my auctions for some really nice examples (Talking Skull) and some rarer books in not such great condition (Death Trap Mince, Monster Mountain).  This is a good chance to complete your collection on a budget!
