Collect Toby from Baker Street, and follow the scent trail | The Abbey Grange Affair SH: Crimes and Punishments Guide

Approach Toby lying near the window and take him with you. Head to Abbey Grange.

As Toby, follow the green trail. Walk along the left side of the room, until you reach a French window. Bark to call Sherlock. When the door opens, leave the building and follow the trail again, towards the fountain. Go past it from its right side and take the path leading to the Shed (behind the fountain, a bit to the right).

To the Shed, Toby!

Sniff the area around the Shed gate, cross the lawn to the left of the Shed and the path leading to it. Behind the fountain, take the path leading to the Well and sniff it.

Now, go behind the Well and go right, towards the Wall. When you reach the place where the trail ends, sniff the Wall and Call Sherlock.

To the Shed, Sherlock!

As Sherlock, walk towards the Shed and cross the lawn to find yourself in front of the gate. Look inside and take the Hook on the left. Examine the Bags on the right, the Tool box on the shelf and Suitcase above it.

Leave the Shed and walk towards the Well (go to the fountain and turn right when you reach it). Open it and look inside. You will notice some Glittering object. Remove the Bucket over the Well and attach the Hook to the Chain. Use the windlass on the left and open the Bag that you've pulled out. You will find an Item of silverware. Take a Fork. Rotate it in the close-up mode and examine the Coat-of-arms.

Deduction

Connect "Silverware Found" with "Criminals Identified". You will obtain two options: "Robbery is the motive" and "Imitated Robbery".

At this stage, you can assume the following Conclusions to end the investigation (the result may not be right): Three People, Randall Gang, Poker Blow and Robbery is the motive.

You can also assume: Two People, Imitated Robbery, Randalls Blamed, Deadly Accident and No acquaintance to end the investigation now (the result may not be right).

When you assume: "Two People", "Imitated Robbery", "Randalls Blamed", and "Poker Blow", you will receive a Conclusion: "Murderous Visitor". Connect it with "Acquainted with a sailor" and you will obtain a task: "Look for sailor".

Return to the house (use the main entrance) and inform Lestrade, who is sitting in the hall, about your discovery. Go talk to Lady Brackenstall and Theresa about the same thing. Then, head to Baker Street.
