The Lego version of the Detective's Office is now long retired. A search for the Detective's Office 10246 on eBay shows that new sets will cost you upwards of $300 USD. But on Aliexpress, I found the Lego compatible set for only $53.13 USD. The set I found is made by Lele and the set number is 30008 and has 2262 pieces. Not sure how long this deal will last, so get it while they still have stock.
