Azeroth's Greatest Detective
Complete two of the following achievements:
Azeroth's Greatest Detective is a 25-point achievement that awards the title Detective upon completing two of its listed sub-achievements, tied to WoW's 20th Anniversary celebration event beginning October 28th.
Start With Alyx
Speak with Alyx at 50.34, 38.71 to pick up the guest mystery quests. New quests become available each day at 4PM Central European Time.
Use Idol Near Group
Use your Idol of Ohn'ahra near the group at 63.79, 51.13, then talk to each group member until they reveal additional conversation topics — they will eventually indicate that the suspect went to the beach.
Search Wavestrider Beach
Travel to Wavestrider Beach near Nat Pagle at 66, 59.44, then use your 
Torch of Pyrreth near the piles of sand. The pile closest to Scrapes contains a dead body. Note that the Torch of Pyrreth is found in your Toy Collection if you cannot locate it.
Confront the Suspect
Speak with Julia Henning, who identifies the undead character as suspicious, then return to Athelton and select 'I think I know who did it' followed by 'It was Scrapes' to complete the quest.
Complete Celebration Crate Quests
To progress through the Celebration Crate portion of the achievement, you must be at least level 30 to accept and turn in crate quests. Collect crates such as the 
Hazy Celebration Crate, Soggy Celebration Crate, and Sandy Celebration Crate, then turn them in to Alyx. Alyx will remain available at a year-round location even after the celebration ends.
Tips
The celebration event does not begin until October 28th, so quests will not be available before that date.
A hotfix requires players to be level 30 before they can accept or turn in Celebration Crate quests.
